It is rather boring, yes. Just slapping some attack and AC bonuses on the class is uninspired. So I will still make my kit. Having read the tutorial... well, it's not easy, but it's not impenetrable either. Looks like it's mostly a lot of work typing things into a text file.
As for Sarevok, I had him in my party in one of my playthroughs, where I played a Neutral Evil Swashbuckler. He was a very solid frontliner combat-wise. He didn't have much going for him in terms of writing, but ToB is generally poor in this regard, I think.
