Jump ability that stays up in air longer to avoid some damage/ability like FFIV but when it comes down it stuns the mob + crit damage WS at same time it stuns the player while the mob is stunned (kind of like having the lance through mobs tail, or w/e keeping the mob/player in place)

High miss rate (still has the evasion from damage/ability for few seconds more so still good to use) but if it hits would be a sweet ability.
