Mouse and keyboard is way superior to the lazy controller.
Let me explain the whole process of tanking with a real life situation.

Fight or flight
Shield lob
Flash
Fast blade
Savage blade
Rage of halone
/l1 hey guys, dude I totally watch that cool trailer on YouTube
Fast blade
/1 yah, wow, my jaw dropped
Savage blade
/1 wait what???? No way bro? Ok let me check
/1 nah man don't worry, I'm tanking right now- so I can definatelly go watch it
(Ctrl+C to Copy a web link someone said in LS chat)
Alt + tab
Open Internet explorer Firefox or google chrome
Paste said link into the web browser
Alt + tab
Rage of halone
Esc
Open up setting and resize to windows mode.
Drag screen over so u can play and watch at the same time!

As yo can see, controller is too lazy, because they don't have a keyboard. Nuff said
