I have been rushing with claws a lot, doing veng and then attack so the running gets delayed. But I suddenly realised that might be glitch abusing?! Can anyone confirm this? Because if yes, my account will be in danger lol :lol:

Nope its just Animation lag.

No, it's not abuse. There is no extra time delay between clicking attack and attacking, just a visual delay; while the animation shows you being stationary casting the spell then shooting accross to your target, your grid coordinates are moving at the normal speed.

Pfew. Thanks guys ;)
