I've just recently started to think about this, since I'm re-reading the AD&D 2nd edition rulebooks in preparation for a pen & paper campaign, but have you noticed how incredibly cheesy the kits in BG2 really are? They are gamebreakers. Take the fighter, for example. In pen & paper games, non-kitted, pure-class fighters are a common sight. In BG2, you have to be stark raving mad to choose a non-kitted fighter over a Berserker or Kensai. There is just no single advantage to be gained. Both kits are *always* better than the true class. And not by a little, either. The Berserker, for example, gets this free "cheese" button which simply allows him to ignore every type of crowdcontrol. Same with Bard. Blades are powerhouses of destruction, almost better tanks than fighters. Skalds are extremely good buffers. But with the existence of these two kits, what purpose does the true class still serve? None whatsoever. That's why I think kits are really cheesy in BG2. On my next "honest" playthrough, I don't think I'll use any of them. It just feels wrong compared to the PnP game.
