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.
Rogue skills are all touch-range. Rogues tend to have lower HP and attack with a very short range weapon by definition. Should Rogue skills prompt an AoO? Should they prompt an AoO even when attacking from behind?
Should every single thing a warrior does provoke an AoO?
