Targeting Proxmitity should be added in

What I mean is for example when playing my ranger my guy targets the mob like normal but if I move my mouse away to target another mob while still fighting I'm forced to again click to force the targeting to go to the new mob

problems this causes

1. Even when you click the game sometimes just does not switch targets maybe its server lag or something else

2. It makes the game feel alot more clunky than it is, The movement isent bad its just we get locked into looking ways we aren't wanting to go abilities in

My observation, which may be inaccurate, is that the game queues inputs.

So if you press 3 or 4 actions quickly, they take time to occur (due to the time required for each attack, action ect).

So if you mouse over a new target the system will not target that enermy untill all the queued actions have completed. Thus the apparent delay.

Its you being quicker than the combined actions you have initiated.
