Ring of Zelos has been bugged for me since the last update. Since Flare changed the way range is displayed from 60% to 3,0. The range actually seems to have become 60:3=20x less.
Tried unequipping the ring on all gear sets and playing a match without it, didnt work.Tried it again and restarting game, didnt work. Tried reinstalling the game, didnt work.
I will keep on trying to find some way to fix this. If any information is needed I will provide it.
