thanks for your inputs guys.
currently inclined to use my legion 100 boost this weekend to try out a rogue, as it seems to be really rare for a dps to have "zero" to very little rng( and in legion we prolly will drown in rng mechanics anyway judging by some of the previews) and i think it should be a decent improvement to only have dps output rng but no rotation restricting rng like i currently have with my warrior where it might even happen that i have to pass a GCD because rngesus didnt smile upon me. (and hell i am looking forward to having some actual burst *smug face*)
and the whole "it depends on your raid" thing at least seems to apply to pretty much every dps class i would consider playing or am playing right now so i guess i just have to deal with that.
that said, any further replies to my OP are welcome as i still have some days to consider
