Not yet at 70 now but if i must i'll pump more resources and get it to 100+ lol.
But honestly the ony way to get exp at these later ratings is to just spam desynth on primal weps as you get around 0.20+ as to only getting a mere 0.07-0.13 rating exp from items
That are like 10 ilvls ahead.
But i've been desynthing i45-50 stuff now ( has about a 70-80% chance of success ) and only been recieving 0.5-0.12 exp or so. Its crazy lol
Already at like 245 desynths :/
Cuz honestly if that means i need to get to 110+ rating i'll be like @_@
Cuz i still need to desynth the warwolf weps too.
