I recently switch my main from a coercer to a gimp ass mystic, for now anyway.
The coercer changes don't dissappoint and the primary function of the enchanter, as we all know, is of course crowd control. Implimenting DPS was a 'cheap' attempt to fix the CC immunizations in earlier expansions. While the dps is good to have, such as healers being given aa lines that increase their dps, they have again reverted to the same problem we had in the first place.
They made control effects at a severely reduced duration which do not provide any relief during a raid, because npc racial spells will cast through control effects as stated in one LU.
I can't give an opinion on how to fix it, just basically restating !! as I gravitate towards.
For the thing about raidwide buffing, can you supply a link to the information, I am not as 'well' informed as others, but I believe that with server populations slowly decreasing as in any game with a long lifeline, you will see less and less of specific classes and need to be readjusted for the amount played.
(i.e. bards having RW buffs, but still roll with 2 dirges and sometimes 3 because of debuffs. Enchanters should still maintain a level of extended functionality past the upcoming and possible changes.)
The hard part, is speculating creates rumors, and rumors create worry, then worry creates quitters. Just keep an open mind about it imo. For better or worse the enchanter will still be a sought after class.
