MCH
- Ricochet gets a similar damage formula has Flare/Holy. Secondary hit deals full damage to primary target, and diminishing returns on damage for every other target afterwards. For a 60s cooldown skill, it's kind of lack luster in everything outside of single target bosses (which even alexander lacks at times). The amount of enemies that can dilute the secondary hit in dungeons and some raid environments really downplays the skill as something you get at level 60.
-More bonus effects on MCH weaponskills/abilities through ammo consumption. They passed it off as one of MCH's main functions, but it seems incredibly under utilized when you look at abilties like hot shot, lead shot and gauss round. It does nothing for the former 2 other than to add 20 potency on the initial hit, and no skills actually require ammo to be executed.

BRD
-Rework Straighter Shot's proc detection. It occurs too late into a typical weaponskill cooldown that you'll never catch the proc unless you purposely delay your weapon skill.
-Rework River of blood to give a stacking buff that boosts the damage of your next Bloodletter or Rain of Death. It'd function better with the cast times introduced by WM.
-Redo/rework Wanderer's Minuet. It's functionally the exact same skill as machinist's GB. It ends up pigeon holing both classes to have the same foundation of gameplay and feels like a really wasted oppertunitiy. They could've done something like have WM to have cast times, reduce GCDs to 1.5 seconds with reduced TP cost, and no damage bonus while enabling the use of Empyreal and Ironjaws.

BLM
-Thunder series is not on GCD but still has cast times. This would allow them to quick cast thundercloud procs without disrupting their enochian timers to a greater degree.
