Suggestions for MCH:

Get rid of our short-lived, long cooldown "support" skills (Dismantle, Rend Mind, Hypercharge). Replace with various turret stances that give these buffs/debuffs as long as the turret is in that stance. This will let us provide a dps boost to the entire party (and offset our lower innate dps) when other buffs aren't needed and allow us to switch to extra damage reduction or MP/TP regen when needed to make life easier for healers, tanks and other dps, providing some true support abilities. Also suggest removing the damage nerf when using regen abilities. Seems counterproductive to punish a class for using an ability properly, especially when they already do less damage than other classes.
