Yushikha ,im not sure what you meant in your respond but il try to answer.
im the last person who actually want all the healers to be the same, so i thought of something to try and help somehow in the current situation and hope that maybe SE will understand and find a way to keep all healers different while maintaining balance.i am not going to defend this idea cause i am not sure it really is a good one but it might start something among the healer community great minds so i gave it a shot and il try to explain it a bit better:
if we take what we have right now with the healers in terms of healings we have SCH+WHM combo is the ideal, AST+SCH/WHM is second place, AST+AST is third and SCH+SCH /WHM+WHM are the last in term of party composition.
however if you take each of the varied compositions for a harder content it wouldn't matter much for the party cause the amount of healings each pair can do , don't have a huge healing gap that could be even considered a problem.(meaning any varied pair will be good to heal for harder content)
so the idea is if somehow there could be some sort of balance in 1 aspect of dps for raids and harder content that will allow varied combo like there is with healing then there might be a wiggle room to allow more complexity and variety between the different jobs regarding the other aspects .
the easy thing i could think of for all healers was utility,if SE could apply the logic they used to healing with the raid utility (like WHM is pure healer,SCH is the shielder and AST can fill both) it might create some balance among the jobs for raids and harder content which leaves just pdps and those numbers can easily be set and adjusted with different dps rotations for each class.
as i said before its the same with healing:
we have AST the buffer and we have SCH the debuffer and a filler which leaves WHM. so if we take AST divination and SCH chain stratagem and give WHM weaker versions of them, making them share a cd and unable to stack with actual divination and chain stratagem ,it might make all class equals for the harder content in terms of utility.
thats only leave pdps and it can allow the unique tools each class have to affect our personal dps appropriatly with the exception of AST cards as i said might make ast lower in terms of his own pdps but he could have a slighty higher number for rdps then the rest of us as long as it wont hurt balance so much that it could cause jobs to be excluded.
again this just me throwing an idea to try and keep the healers diverse while maintaining balance, i won't defend it if people find flaws in it cause even i am not sure.
but i felt to at least tell it and hope it might stir up SE minds to find a way to keep balance while maintain the healers diverse,unique and especially fun.
so if any of the great mind of the healers community,have his idea how to do it let it out,.its always better to let your idea to be heard then none at all.
