Make it 100 problems, then.
Stormblood had:
-Refresh
-Dismantle
-Palisade
-Tactician (PT Song back then)
ShB only has Tactician, a mitigation that does as much as dismantle but twice the cooldown.
Refresh is not needed, old Tacticien isn't either.
But Palisade had its uses, there were phases were the boss would do nothing but auto-attack the tank (Think about Kefka)
One of the biggest problem MCH, it does support DPS but with only one support ability. It goes the same with BRD/DNC, they have rDPS but beyond that their support is fairly weak.
I'm not for a res, it has many problems and there is definitely going to be a "res toll" that will be nothing but a burden when no one dies.
But I'm not against the idea. We lost the ability to make a difference in a group, ranged purpose is to only bait mechanics except there is one mechanic to bait every 6 months. And most of them can easily be done by a caster.
