I'll finally be back home with my gaming rig next week, but was gonna hold off on resubbing until they rolled out Cathar, as that sounds like a decent race for my final class playthrough (smuggler); alas, the upcoming event (Ilum revamp) has me stoked. Between that, a new companion, warzone, space missions and an operation, I imagine I could do a month or more of endgame on 7 lv 50s without getting bored.
Not to mention good PVP gear is easer to get now. Most of my 50s are still in recruit. If I get to chose between tanking/dps sets of Recruit MK ii (instead of what I have just being replaced), I think I'll try and switch to DPSing on most toon. The free Tionese set will also get me started on hardmodes/ops in a new spec; though that content has very limited appeal to me.
