Some ppl might want to get every possible advantage for the Sunwell bosses. In this regard it would be really nice to add close to +6% dps for all group members using
[Drums of Battle] +
[Chain of the Twilight Owl]. And considering less than 5% of end lvl casters have LW atm (And more than 90% have enchanting) Im gonna add more info on this subject.
First of all yes, some of you should probably check out if there are additional raid enhancing profession items that will be added for Sunwell. As for me, I ditched tailoring 3-4 months ago and picked up LW as soon as spellfire/spellstrike bonus wasn't needed. Some ppl also have the luxury/possibility to allocate gathering proffs to alts and simply focus on raid enhancing proffs on the main

.
Drums of Battle
80 spell haste for 5 ppl lasting 30 sec (2 min cd).
Aprox value of 1 haste rating vs 1 spell dmg per class at BT/MH lvl;
Mage 1 haste = 1,07 spell dmg
Lock 1 haste = 0,8 spell dmg - destro (1 = 0,4 for affli)
SP 1 haste = 0,6 spell dmg
Ele shaman 1 haste = 0,9 spell dmg
Example illustration;
Grp with 2 mages, 1 destro, 1 SP, 1 Ele shammy.
Average haste value for given group would be 1 haste = 0,88 spell dmg (+71 spell dmg for average grp member).
-15 spell dmg for individual loss of gdc + ocassional range issues (40 yards).
Constant 56 spell dmg equivalent buff for all grp members.
Average fight length 4 min. 2 drums popped during fight per LW`er.
4 ppl popping 2 drums each during the encounter would be able to make the drum buff a constant +56 spell dmg equivalent buff and would add aprox +4% extra dmg for 5 ppl (BT/MH gear lvl).
In comparison the enchanting buff you get (+24 spell dmg on rings) is less than half of that.
So in fact, LW/drum is 100%+ more valuable than enchanting as a raid enhancing prof. in regards to adding value to raid dps.
And still we see 90%+ of all end lvl dmg casters speccing "enchanting" primarily for the ring buffs, yet completely ignoring LW (Less than 5% of all end lvl casters have this atm).
Chain of the Twilight Owl
If you make sure grp members always have Chain of the Twilight Owl (+2% crit necklace) at all times (1 hour cd so max usage would be every 12 min with rotation) we would be able to add close to +6% dmg to that grps dps (Drums + neck).
Obviously the crit neck can be used more situational since its a lot more expensive but with the low cost of drums I don't see a reason not to use it frequently (20-30g for 50 charges). I use about 30 charges per raid atm. Ive been slacking on the neck though, but will most likely use it for certain sunwell bosses (Depending on boss mechanic and difficulty lvl).
Sunwell is getting closer and we may soon find ourselves in a situation where every little bit of extra DPS will be VERY valuable
