If they are going to allow shield stacking, WHM needs a shield like SCH and AST do. Which will ruin the healer diversity (which is bad right now). I don't think it will be happening and i don't see why it is necessary at this point (other than those ASTs who think their shields are better than SCH and refuse to change to diurnal when they encountered a SCH).

I don't see why SCH needs to lose ET either. It is a cool and useful thing and different than what other healers have. Also, i think shields are there for usage in situations that requires shielding. If you replace everything with a different kind of shield, it would take the mastery of the job, which most of the jobs hurt in SB. It would make things waay easier, which is again, already easy in %95 of the content. So adlo is enough, no more shielding necessary in my opinion.

I think dissipation needs a rework yes, i am not raiding but i didn't use that thing once in 3 years of my SCH playing. It is -%99 of the time- unnecessary. If you know how to mitigate damage and heal properly as a SCH in this game, you simply don't need to sacrifice your fairy, which is soo useful than aetherflow stacks in my opinion (again if you know how to manage it).

Apart from these, i think Selene needs tweaking. -Looks at silence ability-.

I recently started playing as AST btw after so long, and realised how OP SCH still is. Excog, fairy regen and fey union combo can heal the tank up to 2-3 stacks of enemies without you even casting a heal. Which is really distinctive than other healers. More shields, more buffs etc. would break the healers because whm has almost no utility (if we consider what AST and SCH brings), and AST heals are really weak if we compare it to others. So they need to balance things too, and if we were to get more shields etc., the others probably will too and so does the game evolve depending on these shields a.k.a harder hitting mechanics.

Anyway thank you for reading :3
