Server population is better, after mass server consolidation.
If you enjoy a game, that's good. That's enough actually. It could be something you play with 4 people or 400 or 4 million. I'd say that maybe you should be satisfied that it still has any community at all and try to just enjoy what is there. You'll have a hard time convincing people who already decided that they didn't like the game back when it was relevant, to relinquish that perception.
Simple fact is that SWTOR flopped because at its core, it was a ham-handed WoW clone and not a particularly good one. However, that doesn't make it impossible to enjoy, and I would assume the people that found their niche in SWTOR are playing it to this day. Everyone else, not so much.
