Positional should be scrapped honestly. They're not interesting at all. Not rewarding and already at a point where more and more content completely nullifies them anyway.

Knock back immunity I think isn't a bad idea if anytbing I'd say its issue is one of consistency. Of the top of my head ifni made a list the list of knock backs arms length or something had no effect on would be bigger than the ones it did.. thats the problem and why most players never even put it on there hot bars because it rarely works. Why have a knockback immunity that 75% of knockbacks totally ignore... so yeah that is a questionable skill.

My management... well a this point they could go the way ofntp and just get rid of mp entirely they've totally andbutterly killed the concept of resource management.
