I think everyone has a tipping point for every game (MMO or otherwise) where it no longer is any fun for them. I played City of Heroes/Villains for 6+ years and loved it - but when it went free to play - that was it for me. It feels like a Facebook game with all the Ads to buy this buy that. So I left, but that was my decision. As for SWTOR, I like the game alot, but the lack of character customization (i used to spend hours just on my costume), the long, long, long walks between mishes (im used to flying), and the terrible system for finding a group (easy peasy in CoX) is going to push me to my tipping point sooner than later, and I'll go back to city of Heroes/Villains as I'm sure alot of ppl will go back to WoW, or another MMO they like. Overall I'd say the story driven content in SWTOR is fun, most everything else isn't. Without an open world and tools for people to create their own fun (ie: character customization, player cities, choosing your own fing ship and modding it, etc) this game IMO isn't going to be around for long. Once the player base leaves in large numbers its almost impssible to get them back - we all know about SWG.
