Well, I found that Norn’s (maybe other races too but I didn’t test) transform skills (elite skills such as wolf, bear, leopard etc) has a bug.
According to wiki, using these elite skills removes accumulated stacking buffs like Bloodlust from the player. Yes it does while transform, and after transform end, you can re-accumulate stacking buffs again.
HOWEVER, if you die during transform, after rez, you will become back to normal, but you CAN NOT re-accumulate stacking buffs anymore unless you relog.
Please fix it. thx.
