I've heard this game decently solo-able. Is that true? I loved KoToR, and this being an MMO made me sad.
But I've heard mostly good things.
you can go from level 1 to max solo, no problem, and unlike most mmos is has a ton of (decent) voice acting and cut scenes, also since you have 8 classes with different main stories it's a game that is worth making new characters I think,
with 12xp bonus currently (from being a sub and buying the new expansion, until december 2) it's very easy and quick to just do the story and skip the other missions...
swtor is the only MMO I enjoy playing, I never tried WoW but form seeing other people playing it I'm not interested (and the fact you can only play if you always pay the subscription), I tried things like Arche Age recently but... no... I'm always going back to swtor.
the bad thing about the 12xp bonus is that low level flashpoints are almost dead, since people get so much more XP by doing class missions, also 55 hm flahpoints are being flooded with under geared players (like with half the rating required)
