Mobs act weird

[ChangMokei]

Hi there!
I think many ppl has already been telling about this but I didn't find any mention about it from here.
So... it happens that when you hit a mob, it might just continue walking away or even runs away from you and it takes several hits before it goes agro. And then sometimes they agro from miles away.. so to speak... and also they keep on attacking you from very far distance, further away where own skills can reach.
I can live with this issue but I know there are ppl who are more annoyed about it....
