Auto Attack (concerning pvp)

Why did the option for removing auto attack disappear? And when you do a skill on someone you auto attack.. Can this be removed and could you make like a selection to turn it on/off like you guys did long time ago? Cos I need to test something and it wont work if auto attack is activated.

I guess it's new... When you use a damage skill, it automatically auto.. But you can stop the auto by clicking on it :)..

I think it makes PvP simpler and it was simple enough before.
