i got this bug today while using burning vengeance feat if you just click it and not charge it at all it will bug but if you hold it in for a sec and then release it wont bug also if it does bug you can just hold it in for a sec and it goes away till you forget to hold it in that is nxt time you cast it lol
tbh if u just change the daily a little it would be fine the one that ignores def just change it for the pvp side like dragon nest certain abilities do certain things depending if its pvp or pve so could make it just ignore 50% def instead of 100%
