unless you're like that SMN i had in pt, that spammed Miasma II (out of range of mobs) and energy drain, and Ruin...i don't think you need to worry that much.
the only reasons i could imagine for getting kicked, is if you're afk, or as bad as that SMN. Well in primal fights and such, ppl get kicked really quickly, if they try to hijack clear pts, when they obv don't have any experience.
the only issue is the cue times, really.
but yah, just play it if you think you'll like it. you won't get into much problem, unless you're really bad
