SWTOR 1.5 is out, and SWTOR is now Free to Play.
There are now only two reasons not to play:
1: You don't like Star Wars (in which case, you are likely not a human, but a cabbage wearing a fedora)
2: Your computer can't handle it. (In which case, you're Blade)
Five, maybe more.
3. You don't want to play it, for various reasons.
4. It is not the greatest game ever, like you seem to think, and it has quite a few flaws.
5. You'd rather not play a MMO that's probably going to die within the next few years, or not play one at all. (pretty much 90% of all of them right now)

My problem with the world right now is that people are afraid to criticise the things they like because they think they will be mistaken for disliking it, and instead praise it at all costs. But without criticism,
things cannot improve. If you don't know what's wrong with something, how are you going to fix it?
