Hello wow brothers and sistas

Im really getting into WOW again and I was wonder how I might alter my actions bars.

I want them to be bigger, I have a big wide screen monitor that makes my current bars seem so small.. any way I can make 'em bigger?

I mean you can just download bartender or ElvUi for example....

Change the size of the bars. Simple stuff. Not that having bigger bars is a good thing, you should have your key bindings memorized. And set up some weak auras to display major cool downs or rotation priority displays..

Can't you scale them with the reg ui?

You guys use tab to change targets and cycle through your action with 1-9
