well your not alone to be precise. many player's experience it the same way. as many player also quit and stop playing this game due to unbalance RNG. as if its RNG.
i been playing for almost 10months non-stop 24/7, but until now i dont have such better gear enhancement.
wasted bunch of resources, even wasting cash for the sake of RNG. or even Luck. 24hrs grinding and farming is no joke if the basis is RNG.
ever since I've achieved Awaken enhance of HEX, i haven't reached the HEP, now every time i enhance my gear, it looks like enhancing a Totem
thus also my totem lock @ +6 after bunch of trial to reach at least +7 no luck
anyway still, a good game for me.
