Getting WHM on Par

[Brightshadow]

People will cheese mechanics this way regardless and it'll create a divide where whms will be favored in raids more

Doubt it, in theory if the WHM was to survive a death mechanic and the MT survived as well the WHM wouldn't have the mana to raise everyone nor heal at the same time. This would only help if the boss was at 1% and somehow the MT survived. If all the tanks are down and your the only one that reraise most likely the trial would reset but let's say it doesn't the boss would hunt you down and you wouldn't have the mana to raise the tank, and even if you do raise the tank you'll most likely be dead by now and the tank would be at low HP leaving him for dead.

SCH DPS would still be favored over Reraise, and AST Cards would still be favored over Reraise. the only thing it would do is give them something a little niche that still wouldn't push them beyond SCH/AST.
