Played SWTOR on release, reached level cap and was in highest tier PvP and PvE gear within 3 months. Also realized how bad at balance Bioware was because tank Assassins COULDN'T be killed and pretty much made every PvP fight an instawin.
Also made $50 bucks from the game by selling my black-green crystal (I was the sever first to get it in the Rakghoul world event) to some kid about 2 months after I deactivated my account. Went back on a couple of weeks ago to see what this "free to play" business was only to realize that i couldn't wear any of my raid or pvp gear (or any other epic gear for that matter) and it was all in my inventory and I had to pay if i wanted to even wear my gear that I previously spent hours grinding for last summer....
Bioware sucks at making MMO's in my opinion. The stories ARE really fun though, thats what they did do right with the game. But end game balance and lack of content drove me away after i cleared everything with my guild within 3 months of release.
