From rdx-raid.com by Veneficus, the author of RDX:

So, what this change means is that mods cannot be used to cast spells, meaning that stabbing buttons for decursing and buffing is no longer allowed. Point and click healing functionality is still fine, obviously. I'm not paticularly bothered about this change myself, provided they don't create any more lucifron/chromaggus/noth style encounters, or if they do, mass dispel will be fine.

Of course, this has the added side effect of making old encounters much more challenging post expansion.

Thoughts?

For the first part, it says "during combat."

This wouldn't affect buffing, as that's done out of combat.

Would affect whispercast buffing for paladins, which is a bit irksome when you consider increased power of off-specs for the hybrid classes will lead to vastly different blessing interests (see the enh shaman blessing thread).

Overall I consider it only a positive if it means the death of "decursive fights" like the aforementioned MC/noth/chrom.

On a more humorous side it's a slight nerf to warlocks since there won't be stupid people spamming decursive and procc'ing unstable on themselves :P

This will break far more mods than Decursive. It will break all click to heal mods (emergency monitor, Clique, etc.), hell it will even break FastCast.

This seems so far a good change.. I'm not sure exactly yet.

Clique makes healing not an utter chore. I dont mind so much the breaking of decursive or anything else, but breaking of so many other nonabusive mods seems going a little too far.

How on earth can they do that without removing any ability to use any ability from a mod, period? This change is going to break almost every mod if it's implimented :o

Mass decursing has always been the worst part of WoW, as far as I'm concerned.

It would be nice if it promoted intelligent debuffing ("Hey! I just threw Curse of Splat on the entire raid. But you only have to remove it from the rogue highest on the aggro list! - good raids spend 1 decurse, bad raids 25! of mana"), but instead, it's just "hey, let's assign decursers."

I thought the idea was to make the game more accessable - this gibberish is EQ leftovers of punishing your playerbase. Look, Bliz, people who hate themselves are going to leave you for Vanguard or whatever anyway. And then you'll only have 6.9 million subscribers. Somehow, I think we can get through that together. It's time to move on. Let them go. Move on to the new girlfriend. The 6.9 million player fat girlfriend.

I'm not exactly sure, can anyone explain?

Does this means this change might break the default UI windows (for targeting) or CT_Raid's small raid windows for healing as well? (I'm not talking about Emergency Monitor.. Just the small windows. A bit like the one you can get from default UI.)

So basically, you can't for example click on a target's raid member frame, then click on says, T to cast a heal spell?

(If it's the case it's quite horrible.. If it's not, I don't mind I guess I always select/presskey to heal..)

Breaking fastcast and trinket macros seems like a really, really shitty deal to me, you know. The amount of latency we deal with on our servers is pretty massive and fastcast and trinket macros are the only things that allow you to get decent throughput on 500ms connections. I hope this change gets severely curtailed.

This is a massive change to the game. I'm quite happy for them to "break" decursive, as it has never really seemed to be an intended gameplay mechanic, but the impact to other mods are immense.

This is what worries me the most so far. As an Aussie, this mod has been an absolute blessing.

I hope that a middle ground can be found...

No fastcast is basically the end of the world for a lot of players. Here's hoping that some kindly Blizzard folk are reading this and taking notes before they go and add a fifth of a second to the cast time of all of my spells.

Decursive they have always hated ... but it only exists as a response to terrible encounter design where the whole 40 person raid needs to be decursed against the clock

Auto rank selection ... its not really an effective way to heal anyway so I for one won't miss it

Single click casting (i.e. Single spells assigned to mouse buttons) I will miss a great deal - again these mods exist mostly because the default UI is weak. It enhances the fun in some way to have to do the same operation hundereds of times a fight with 2 clicks (or click + key) instead of one?

There is a new Interface option called "Enemy Castbar".
If you activate the "V"-key casters will now have a tiny castbar under there healthbar with a icon of the spell next to it.

I agree, no fastcast makes a huge difference.
I would hope if they are breaking it they include something by default which amounts to the same thing.
Currently for an Australian (or equiv) fastcast makes a bigger DPS difference than a complete tier's worth of upgrades :(

I have always felt the same about Decursive, if the initial MC encounters hadn't been so stoooopid there wouldn't have been a need to write a mod like it.
