Sunwell is the last raid of the game, after Black Temple. The hardest raid of TBC.
Until there, it is not needed.
World buffs were more important than Drums in terms of POWER.
You will probably be able to complete Sunwell without them as well.
Also, remember what Blizzard said:
So, they won’t nerf Drums, because that would require re-tuning Sunwell down, and that wouldn’t feel a classic experience in Sunwell.
Therefore, makes no sense, at all, nerf or add a debuff that never existed in first place.
Adding a new recipe for the “better” version of drums down the road will remediate the situation for those people with weak-mind/emotional state that cannot make a decision for themselves and need someone else to take the reins of their lives and decide for them.
That is, if you don’t wanna get LW, then just don’t do it. Do not look for a guild that is asking players to use LW. Make your own guild. Play with your friends.
If you can’t deal with making your own decisions, then don’t bother others with your problems.
