ok here is the thing dude
1.- Wastrel sword is NOT BUG enchanter Lighthing Hands buff gives 1 extra hit in your AA and that extra AA is Strike! the skill work like that is not a bug at least atm and wastrel sword say Strike atack dont care if is distance or not try it only AA proct the buff and not skill so wast is used to boost AA only.
2.- Cap is 60% if you use leather yes but here is the catch appraiser skill give extra % legend marnox gives extra % some skill like pistol shot gives extra outside the 60% and if you have a good pt composition the skill than lower critical resist help that 60% the remain 40% shrinks (is not like it bosst critical rate but boost minimal critical chance buffs so) and if you got a amatador fencer in pt or a miko UFF yeah cap is 60% ALONE not using skills so take that in mind ok?
