Trooper story is boring :/
Consular to enjoy it, you have to play Dark Side. Preferably assasin
Imperial Agent story is the best.
Smuggler is funny at the start. (especially around Nar Shadaa).
Jedi Knight meh
Sith Warrior is OK. However when you arrive at Hoth, the cut scene with Vette is all the money.
Bounty Hunter, surprisingly the only one I have done twice (Merc & PT). Worth to play it with Rattataki Female and go full Dark Side.
Not sure I agree with some of this.
Consular, for me was the weakest story, though still not bad.
Imperial Agent story is the best, yeah I can go along with this.
Leveling a new Jedi knight right now (level 2) so will see though I have leveled 3 I forget quite a bit.
I like the trooper story, though that might have a bit to do with I like the play style of the trooper.
I like the bounty as well, but again the style of play influences it a lot.
