i've been playing the original NWN up to Bard 6 / Fighter 1 / Rogue 1 using a half-elf, and now i'm planning to level up on rogue to bet 6/1/2.

My questions are:
1) I've read that half-elves don't have favored class so they don't suffer from xp penalty. Is that also true for "triplet" multiclass like i have?
2) Is a Bard 6 / Fighter 1 / Rogue 1 the same as Bard 6/Rogue 2/ Fighter 2??
or are there some differences??

Thanks a lot
