When I was in school if you annoyed my gym teacher (something that was surprisingly easy to do) he would threaten to "rip your arm off and beat you to death with the soggy end". Maybe that's what Cyric did to Bhaal?
Beyond fixing bugs and upgrading the engine to speed up installation and prevent crashes I think all the changes and added content should have been made optional. I never used to play with mods beyond the Baldurdash and Dudleyville fixpacks and the EE version has introduced a lot of things I would rather not have.
What I would have liked to have seen would have been an option screen asking you whether you wanted to mod the game. Something along the lines of:
Do you want new NPCs? Y/N
Do you want new kits at character creation? Y/N
Do you want to play with BG2 sprites? Y/N
Do you want to replace the movies? Y/N
Do you want to give Gorion a Belt of Antipode? Y/N
Basically, I would have liked a smooth-running, unmodded version of the game with optional downloadable content. That really would have been an Enhanced Edition.
Daggers can be a good choice in BG2 because the same proficiency covers throwing daggers as well as melee weapons and there are some really good magical and poisoned throwing daggers in BG2. So choosing Daggers gives you a double whammy as it were.
I remember clearly the first time my character transformed into the Slayer. I wasn't at all happy about it. It suddenly turned the character into someone I didn't want to be or want to play. I've always really disliked the whole Cthulhu thing so when I suddenly turned into a creature that looked like it slithered straight out of that mythos some of the magic just went out of the game for me.
I know it makes sense in plot terms, you are a child of Bhaal after all, and if you are a descendant of the Lord of Murder you will have some pretty impressive inner demons, but after that point I really found myself playing to find out what happened rather than because I was enjoying it.
