Neither did the cleric/thief.
Pausing in the inventory is, IMO, wrong. The reason a fighter has four weapon slots is because that's the only thing he has in his belt.( and don't tell me your character keeps his two-handes sword on his back. Drawing a weapon longer than your forearm from your back is humanly impossible.) The mage, on the other hand, has spell components, a spellbook, yadda-yadda-you-get-the-idea. But yes, at least 2 weapon slots are realistic.
I agree that the BG2 engine is slightly better with kits, sorcerers, tab key and what not. But the artwork isn't nearly as beautiful. Neither are the avatars or paperdolls. Or shields. A flaming fist mercenary just didnt look right in tutu. And since when did shields have pointy shit sticking out of them?
In my opinion. hehe
