As much as i hate PA (the skill) i dont think outright removing it would be as easy as it sounds. Or maybe it would, who really knows, but i still think it would have drawbacks aswell. I much more would like to see it being used more strategically. Giving it to shai sure would solve some problems cuz you cant really stack them (in before they buff shai to be as strong as wiz). I also could see a world were you get a debuff once you got PA that lasts like 5 - 10 minutes, in which you cant get PA again, making wiz stacking somewhat pointless. I heard many solutions to this topic, some good, some really bad, but any change to change the meta a little and give the game some fresh wind would be nice.
