if you look at representation by spec resto druids need a good bump…least represented of healers in a raid and first to either sit or go boomkin when you’re moving down under 4-5 heals…
For example in the last 2 weeks on Algalon there have been the following parses:
Holy Pala - 24653
Disc Priest - 13949
Resto Sham - 9797
Resto Druid - 7414
Holy Priest - 1628
Ignoring HPriest as they have a second healing spec (even if you dont like playstyle) resto druids are at less than 40% of the representation of HPala and 70% of disc priest (only because you cant really stack disc priests). RSham arent in much better shape either.
Looking at Ulduar as a whole it looks even worse which is RDruid is 50% less parses than Disc priest and 70% less parses than HPala. Meaning you bring 1.5 Disc priests and 3.6 Hpalas compared to 1 rdruid by parse count.
