Well, here's the deal. I like thieves. Like... really like thieves. However, I always tend to dismiss the Swashbuckler almost immediately because of the one thing I love about thieves: backstab.
Now, I'm pretty used by now to soloing the game with crazy duals (that is, dualing at over 3 million xp, to milk every last bit of power out of the first class and then taking them to ToB to own the place).
I have found great success with this, and it makes it a very challenging game when say, you're a level 1 thief in the Underdark
However, I've never taken a solo thief to ToB
But back to the point. The way I see it, I believe the Assassin/Cleric would be the one that has the potential for absolutely obscene backstabs (without cheesing or criticals, you can get regularly upwards of 150+). Where as the Swashbuckler/Cleric really "only" has +6 Thaco, Damage and AC over the A/C. Now that is not something to sneeze at, considering the A/C can buff himself up to 30+ damage per hit power without those bonuses (and with 7 APR to boot: 1 base, 1 off-hand, 1/2 Gauntlets of Specialization, +1 Scarlet Ninja-To, doubled by Imp Haste from scroll, cloak or amulet).
But then again, are these bonuses worth the loss of backstab? I've read all over that in ToB trying to backstab is futile. But I've also read you need a +4 weapon in ToB otherwise you can't hit anything (absolutely false).
So my question is, has anyone used backstab effectively in ToB? Cause if that's the case, I think the A/C takes the cake.
Anyway, opinions, stories, anything?
