Auto attack and possible consequences

[Physic]

That kinda goes against the whole reason for them wanting to implement auto-attack.
The manual attacks require a lot more back and forth between client and server, where as auto-attack is like this.
Client: I am engaged with x target.
Server: You attack for x amount.
Server: You attack for x amount.
Server: You attack for x amount.
Server: You attack for x amount.
Client I have disengaged x target.

The current system has client sending attacks for every server result.
It's very inefficient from a bandwidth and processing aspect.

uhhhh other games have no problem with this, i think they are instituting auto attack more to appease people who dont want to press buttons, or overpress the buttons.
I hear wow, you almost never auto attack, Aion you were almost always using skills non stop, and it was able to be recreated even by private server users. Psu/pso had instant attacks (though this only had like 5 people in an instance in a time so i will let it slide) guild wars, was basically fast paced skill driven.

I just dont think thier server problems are related to auto attack, or if they are, its a problem that other companies have solved.
