I'll take my time leveling my alts, I don't plan on playing on just one toon like I did on WoW with my rogue before BC. Spent all my time raiding, and pvping the first year of that game. I like the stories in ToR to much to burn through it, even did a day of the MoP beta,,can't really go back on reading text just doesn't have the soul ToR has.
I've tried and canceled, Aion-STO-Rift, and they couldn't keep me in their worlds. I play on Jekk Jekk Tar as Republic mostly, have one Sith for the Sith race. Hyperspace Cannon is my Imperials toons, haven't started their legacy on there yet.
With the Legacy System to have your toons connected is one of the greatest concept for Bioware to come up with. I have my Legacy at 15 now, and I plan on staying.
