Refering to the news on MMO and the changes to DS und SoB, will we use DS on single target? Because there is no notice of a shared CD between DS und CS (like Prot have with HoR and CS) and 60% weapon damage every 3s to 4.5s seems to beat out judgement or at least holy wrath, doesn't it?

It may not actually be 60%. As was just posted on MMO several abilities now change their weapon damage percentage as you level. So it might be 60% at level 20 and 150% at level 80. Also currently it's one chance to proc DP per cast not per mob.

Despite it not being mentioned on MMO-Champion, CS and DS do indeed share a CD on the beta, as was the stated intention.

I am in the beta and I can confirm that, as a level 75 Paladin, it's still 60% weapon damage. The change is good from a philosophical point of view, it does mean that we can use this AoE as soon as needed but the damage needs a bump, at least 20-40% from here.

I was disappointed in a couple of other things. I thought Divine Plea was meant to provide Holy Power to everyone and it would have been very helpful for us too, but in reality it is only through a Protection talent that this can happen.

Anyway, the worst thing actually is about Lay on Hands. In the 13183 Beta Build ( MMO-Champion - Cataclysm Beta - Build 13183 ) , it was specified that Forbearance effect no longer includes Divine Protection (which is true for live as well) AND self-targeted Lay on Hands. However, this is false on live and, as I just found out, false on beta as well, which is disappointing to say the least.

Good things over live include Hammer of Wrath proccing Divine Purpose (this is great, actually) plus a new Crusade talent effect: after killing a target worth either experience or honor points, for the next 15 seconds Holy Light heals for 300% more. At level 75, I have 11k Health Points and it heals me for 13k non-critical...Maybe this could be somewhat lessened, and Lay on Hands should seriously stop causing Forbearance.

DS at 60% seems reasonable at first glance, since CS is at 150%. DS on 1 target is 60%, DS on 2 targets is 120% (plus 2 seals, still should be short of 150% + 1 seal), DS on 3 targets is 180% and it pulls ahead. However, this does not take into effect Crusade. With Crusade CS is actually at (150% * 130%) 195% weapon damage. DS might possibly pull even at 3 if the 2 extra seal procs can match 15% weapon damage (unlikely, to be honest), otherwise it requires a 4th target to even consider using. Increasing it to 65% makes it match CS at 3 targests (65% * 3 = 195%), 70% is probably a better choice.

I do wonder about the fact that with 20 targets it's a ton of "free" AOE considering the cooldown. I rather expect a target limit (even if a largish number like 8). That 20 target scenario (rare, I'll give you) also would provide a boatload of free healing.

Even if it did receive a damage bump at a certain level, it would be undesirable to use while leveling unless you had 4+ targets. It needs an across the board bump (or gain from Crusade).

CS (base) is 115% since Beta Build 13221 (MMO-Champion - Cataclysm Beta - Build 13221).
Anyway, DS definitely needs an across the board bump, not only a high level-bound one. Unfortunately I can't post at all on the Beta forums, I login and the system keeps telling that I have no Cataclysm account attached...
I wonder if that's because the forum beta login is technically on US servers and my account is European, although in that case, it would mean no European beta user can provide feedback.

I've logged in with my 85 premade and DS it's 60% weapon damage.

I did the math on DS and it is worse even at 5 targets. The problem is that CS procs a 3 target seal cleave and 3 target SoC which raises its damage dramatically. At 85 with starter raid gear and normal buffs your SoR CS is going to do roughly 4.8x the damage of DS, so DS pulls ahead *marginally* at 5 targets. However, that is ignoring the fact that CS gives a full Holy Power and DS gives only .4 of one, so I am quite confident that DS is not useful until 7 targets. At 60% DS will only be used in true AOE situations with hordes of mobs, I doubt it would even be worth using in heroics.

At 100% DS would be equal to CS in raw damage at 3 targets, but again the Holy Power issue probably means that DS would only be an improvement at 5 targets. To make DS to be the best button to hit at 4+ targets they either need to make DS generate a Holy Power automatically or raise its damage to the 110-120% range.

Further empiric testing shows that, despite the 235% "increase" claimed (MMO-Champion - Cataclysm Beta - Build 13221) over 225% supposed previous value, Templar's Verdict deals less damage than live.
Hammer of Wrath is also evidently lessened but this can be understood, on live it is vastly exaggerated.
Exorcism does more damage, however maybe some of the three main physical skills (CS, DS & TV) could use some bump. They vastly nerfed our damage and improved the healing beyond any real need...Holy Light had a substantial buff to base, plus Ret can count on Crusade talent too, as 75 I critted 19-20k Holy Light; I think this latest beta tendency should be partially reversed.
I just found that Hammer of Wrath isn't proccing Divine Purpose at all...I filed a ticket for that.

On a sidenote, there are some cosmetic changes to spells: Seal of Truth and Seal of Insight are slightly changed (improved, arguably), the same can be said about Divine Storm which if I am correct has a new sound as well, but the most evident of all probably regards Hammer of Wrath: the energy hitting the target is now red, instead of the usual "sparkling light" color. I'm not sure which one I prefer, to be honest.

This is more an issue of the seal and Holy Power mechanics rather than DS's damage itself. It clearly should generate Holy Power equal to Crusader Strike. Functioning off of DivPurp is a severe weakness and another dance with the RNG. Causing DS to proc a seal cleave on a "primary" target (the one that currently procs DivPurp? No HP is generated unless you hit a target, so this must be feasible) and then individual procs on additional targets would also resolve the seal issue. It would functionally become CS which hits multiple targets, proccing single seal on each additional target, plus a freebie healing component. One would hope this would be Blizzard's goal. CS for single target, DS for multi-target (probably 3 target breakpoint) and the heal is for flavour and because a talent point should be worth something.

If DS remains this weak, it may be optimal to use 2 points in EfaE to reach Zealotry, then the last optional point used for utility (Divinity, Acts of Sacrifice, hell, even Clarity of Purpose for PvP)..

Edit to clarify: By the talent suggestion in last paragraph, I mean by skipping DS as entirely useless talent.

It's worth noting that the recent beta build changed the activation requirement on Chaotic Shadowspirit Diamond from more blue than yellow to more blue than red.
