I think there was a change in the last updates. Not sure here but its kind of annoying now to run if you hold the mouse. Everytime i hold the mouse key to run i auto stop as soon as the cursor is at a mob. This should be kind of changed how it (was?) or is in other games.
If i want to a attack a mob i can just click again but it should not stop as i´m auto running while holding the key. If i have close range skills i want to run close to the mobs but often there is less space to run between so i auto attack (Staff range). This should be changed.
