Here comes the bubble burster with needle in hand to burst some bubbles!

-BW during grit would make DRK the go to MT because they'd do the most damage by far
-SwO 10% damage increase would make PLD stronger than WAR....that does sound nice
-Reducing the CD on Duality & Dwd would make NIN stronger, which would give it support AND damage...again maybe not the worst idea.
-WV 250 potency aoe? 30 second recast? Sidewinder is a 250 potency with both dots on the target & a 60 second cd, way too OP
-MNK being able to use chakra in battle would SKYROCKET their damage, Forbidden Chakra every 10 seconds? OP. But if they somehow made it so you could only use Meditate, then it'd be very useful.
-Stoneskin 2 was only added later to make it easier to stoneskin everyone before a battle, if WHM could use it battle at no cost, that in itself is OP, still sounds reasonable-ish, but might mess up end game raids/ex trials

However commends for actually trying, I love the influx of ideas
