I've not quit SWTOR and don't currently plan to, but I realised recently that I have been playing a lot less. Perhaps this happened a little subconsciously, as there's been no real thought to it, it just kinda slowed down and I got distracted. My main is fully purpled out, I can compete well in PvP, I've cleared all the hardmode instances I've been in, cleared the Eternity Vault raid (though I'm not much of a dungeon farmer anyway) and Ilum remains a total load of bollocks. Also as an Empire player the warzone we normally end up with is Huttball, which is getting very old, particularly when wins so often don't register on the daily mission. Really I just want Ilum to improve, as that's theoretically providing the type of gameplay I really like (as per DAoC, WAR, etc) but I have serious doubts there.
I have started a proper alt, a Bounty Hunter Mercenary, but I'm not diving full on in to it just yet and not getting that MUST PLAY NOW itch. That said, I have also got a load of major stuff going on in real life which is souring my mood somewhat and as such everything seems a bit shit. Perhaps the fact that I'm mainly spending my gaming time in games where I can be building things, rather than see them destroyed, is fairly telling.
Which leads me to mention the Kill Frenzy Minecraft server has been reset with all the lastest patches and I've found myself heinously addicted... again. When not exploring and fighting stuff, I'm building a multiple tower, sky garden, thing... As everyone knows it is a magnificent game and an incredible time sink, pus I'm a real sucker for exploring and marveling at the cubist beauty of its randomly generated terrain.
Anyway, as I alluded to above, I'm not done with SWTOR yet, but I have run out of pressing targets and am now at the point where normally openworld PvP / campaign RvR would take over. Which unfortunately are SWTOR's weakest points.
