Last post was good. Explained it all.
Personally though?
I like the Trooper story. Light or Dark, though Dark is more interesting.
Inquisitor...? I wouldn't say its bad... But it does drag on lots, and you're running all over the galaxy... Tedious at most.
Only class I haven't really leveled is Night and Warrior. Working on my Consular.
But imo, Bounty Hunter, except Chapter 3, was best. Though everyone will debate it. Its personal prefrence...
End game Bounty hunter 55-60 is best so far though. Has way more dialoque and story then other classes.
