they are not gonna remove ruin II from scholar's kit. energy drain really isn't anything wrong with it. just needs some fine tuning a little probably making it feel little better then it is now . scholar players shouldn't have worry as much as they are. all i can say is that scholars aren't in a bad situation or as bad people are saying. job reveal was a awful visually but technically there pretty solid. my only concern is animations of these abilities are appealing to scholar player compared to visuals that other classes have gotten. but miasma and bane is something heavily talked about and discussed with healer dev's it take little to for them put a patch up and you getting those abilities. no reason for them put them on job revealed trailer specially when nothing really changed about those abilities only the job that has them.
hell you might as well get upgraded trait version of ruin II on scholar. but no there not gonna remove it from scholar or energy drain they just change the numbers. however white mages version ruin II they get is completely different yours shares global cooldown with ruin. but is spam able. however from knowledge ive gathered white mages version requires a trigger to be able to be cast. doesn't share global cooldown can be weaved between glare cast. but has proc chance so rng heavy. there for its not used in same way as scholars rune II even though they seem somewhat similar
however if scholar has bane and new art of war your aoe dps is pretty much covered on scholar that and having miasma back giving double dot. ability to spread + art of war. having really fun aoe rotation
