Oh yeah STabbey good point about not all spells should provoke an attack of oppurtunity,the point about rangers isnt that they shouldnt get a free pass, but the play style of keeping them out of harms way to prevent attacks of oppurtunity is a players tactical perogative, if they stand there in range and stupidly shoot then they should get hit anyway.

However I disagree on touch spells...thats an attack and if you move into range nad have ashorter weapon well thats the fault of the toon trying it.
Touch attack spells should provoke an attack of oppurtunity if they get in range of the someone who can swing on them, it is no different than any other attack, if I was a swordsman and some little geek tried to get up close to give me a pat of encouragement, I am not going to ignore him.

Healing spells and escape/movement skills or spells should not provoke an attack of opportunity for precisely the reasons you gave. On this I agree and had not considered it until you brought it up.

I am not confident that Larian will change anything about attacks of opportunity, but I really wish it worked more like it did in Temple of Elemental Evil. It made it so even a fighter that is doing nothing is practicing area-denial. As it is now I dont think it works that well, it certainly in my case seems to only happen about 25% of the time it should happen. I hate that someone with a shorter weapon is able to rush up and hit soemone with a longer weapon with little fear of being whacked, same for someone using a spell or shooting.
