changes to resolve
replace the recovery mastery with perseverence. perseverence isnt strong enough to be a keystone anyways, but at least it scales. 2hp5 are just a joke.
tough skin should be a 2% to 3% resistance bonus against basic attacks. maybe even more. just add the 2 flat against monsters to jungle items directly.
perseverence can be replaced with adaptive armor or 10% crit damage reduction.
