I've recently beaten BG1 and BG2 with a couple of friends - good times! Playing a spellcaster I found it absolutely essential to have all my spells bound to specific keys in order to ensure a fluent multiplayer experience though (i.e. minimizing the use of the pause button), but this seems impossible in IWD2?
If anybody knows how to keybind spells, please let me know. If this is impossible, then I'm very interested to hear what you guys do in multiplayer when playing spellcasters? =)
