I myself never made a problem out of paying ?10 a month for a good MMO, it helps them maintain the servesr, and really, in some places you can barely get lunch for ?10, a good MMO will give me more enjoyment than that lunch and it'll last me longer.
And well, I don't mind the artstyle of The Old Republic, it is a good deal more realistic than the Clone Wars CGI show, or even Team Fortress 2, while still having some stylised proportions. And well, when you invest as much cash in a project as in TOR you do want as many people as possible to be capable of playing the game, and let's not forget that this game has been in development in secret since 2006, the engine is almost antiquated by default by now.
So the choice to go for stylised art was probably made for a variety of reasons, but hey, after following the game for two years... perhaps even three, I can safely say that I've grown to like the art style, I can understand that it's not for everyone, but hey, nothing is. I'll take stylised characters over uncanny valley "realistic" characters any day, though.
