as much as theres lots of people quitting healing here all i see is an extremely jumping number of healer in jp server, it used to be a hour or two just waiting for healer to come for weekly savage now healer is tge first one to fill, so yeah the healer population is jumping at a superb rate here, my main who is an SMN also using healer to do weekly savage since a monyh ago, so i must the if the reason of healer simplification is to raise the population, they are succuss in it.
(tank however, decresing in population for oversimplification xd)
