Geromino: Well, I really dont like monks. They are bad enough in D&D3 already. But the implementation in BG2 was so bad, for example monks dont even get good saving throws there.
I've played Sorcerer (endlessly), F/M (once), Paladin (once). What can I say, its a really super long game, one playthrough takes like a month.
But I definitely dont remember ever thinking on my F/M "oh this is better than Sorcerer". It was more like "dammit when do I finally get my level 9 spells already".
I was surprised how super strong my Paladin ended up. No spell seemed to be able to touch her in the end. She just won every saving throw, with reliability.
The fun of Sorcerer was simply optimizing their spelllist.
I once tried playing evil and for that I picked Necromancer. I was quickly annoyed that Edwin was so much better than me, though. Also, boy is it hard to play evil. Still the evil NPCs in BG are so funny, lol.
