give casters their own version of swiftcast/protect. give dps their own version of b4b/ir. this will opens the way to make it more unique to each job (maybe nin's b4b also makes ninjustus stronger, mnk b4b makes gl lasts longer?)
a lot of jobs are already pretty full on keybinds anyway, just make 4 of the 5 skill we get on the way to 70 the replacement for the common cross class skills with lvl 70 skill being the brand new one
