first off, i wanna ask same thing, but different situation, hempen yarn as a 50 weaver with careful synthesis 2 and full hq af gear fail 10% of the time

second, i wanna add in, for this game, we do not call it the RNG, but rather the RFG (random f***you generator).....or maybe its just me that feels this way
i make that statement based on hq success, not the quick synth that i knew was bad for success rates
