Rito pls, add in ping to the client!

All the time I find myself going into games to find that my ping is 300+ when just the game before it was 80-90. What I've been wanting to see for a long time is prevention for this, because everytime it happens I say to myself "If I had known my ping was this bad, I wouldn't have gone into a game where I can be banned for being DC." Does anyone else agree?

It would just be a simple little thing near all the other summoner related stuff on the client that would tell me what my current ping is like without me having to use command prompt to ping servers.

Thoughts?

EDIT: To repeat, I want to see this IN-CLIENT, so that you prevent yourself from going into games when you have lag. I know there are other methods, but having a quick glance ping should be easy to add to the client and will prevent you from leaving your team with a 4v5 and you get banned because you couldn't tell what your ping was before you go in game.
