Please Please Please Optimize Keyboard/Mouse!

Simple as that. Please Optimize it. I find it incredibly difficult to target monsters. Start Auto-attack. Ect. I can't understand why I have to tell the game I want to attack something three times in order to make my character start attacking. "I want to fight so go into battle mode (first button passive/active mode)" {now I'm in battle mode yes i can fight! oh wait.....} "I want to fight that one (second button - left click)" (ok cool you are in battle mode and you want to fight that one but you STILL aren't attacking) "YES FOR GOD SAKES START ATTACKING (third button - left click again... you would think a fast double click would work but no you have to wait like 2 seconds before the second click)" {yes this is what i'm thinking every time i hit the THIRD button required to begin fighting something}

Sorry for my rant but this is how it is right now for keyboard/mouse.
