the PA bug with skills buffing but no effects is because of the skill u get after u die. protection of the guardian. manually debuff that buff and then u can buff your buffs and actually get the effects.
go ahead say thats not it.. then go PA tonight and try it.. hit C look your stats/melee/hp while buffing with protection of the guardian on.. nothing changes. then debuff it and rebuff and look stats/melee/hp.
as for the mega misses i have no idea.
duno if any1 else knows this.. no1 has seemed to post it yet. i was spamming it on my side last night but idiots didnt listen and kept buffing with the gaurdian buff and wondering why hitting so low.
until gms can figure out how to fix that maybe they shud just take that buff off.
