Ouch indeed.
I played SWTOR for about a month and a half. If you were on the F2P system, it was likely a frustrating experience with run/sprint restrictions, credit caps and other annoyances.
That said, even with preferred and sub status I found the game to be entertaining but lacking something.
I think i went in with decent expectations as a long time WoW veteran looking for a decent f2p alternative to kill some time, provide some entertainment and satisfy my quest for purply pixels. After that month or so, and leveling numerous characters I just found myself with nothing inspiring to do. Storylines seemd like they were good on paper, but the whole light/dark side thing didnt seem like it really affected much of what you did. The individual stories seemed as if it were on rails in that nothing you ever did really seemed to change your character's development (in the end there may be a handful of choices across all the characters that change anything). Had way, way too many bad tank/healer experiences. No auto attack for "white" attacks was also something that I could never adjust to. Dungeons had a hilarious difficulty bump around 40 that made queueing for them pointless.
So I ended up resubbing to WoW after a multi year break due to wanting more out of an MMO and knowing my old guild mates were still online and enjoying the daily grind that is MoP (and it is most definitely a grind when you reach level cap)
I went OT, but figured I would chime in. I say if you had played before, give it a shot via rez scroll. If you're new, new ... find someone ot refer you so you can get crazy xp gains and other benefits. I believe you get 30 free days with the battle chest (or at least you did previously) which gets you through WotLK. Cata content blows by with the xp requirements being reduced. Last patch also made MoP content go much faster with a 33% leveling XP reduction. So you can hit level cap fairly quickly even as new.
