Updating the HUD in-game

What do you guys think of adding things like debuf timers and auto-attack timers to the HUD? I think it would be a nice addition to the game. For example: when I'm playing I like to wait til my passive debuf is about to run out so I can quickly refresh it and then e, but with having the UI small I can only see the debuf timer on the top left screen and it's very small and almost impossible to micromanage it. The auto-attack timers would also be nice for people wanting to practice kiting. Maybe even just having the option to implement them into custom games for practice on last hitting and such. I dunno, seems like a good idea.. Kind of like WoW addons if you will.
