See Teammate Champions

Isn't it about time Riot implements a way to see our team's available champions?

We've all been there; Solo queue, you've got the first pick, your forth teammate wants Yas but he'll never last that long, you pick Yas to swap, you then spend the next 4 minutes typing frantically trying to figure out what champions he has. Or you don't want to be countered, so you work out a trade with ADC, spend next 4 minutes typing frantically...

It seems like such a relatively simple thing to do; pick champions and trade them. Yet, it's an ordeal nearly every time, to the point where most people will simply remain silent when asked "hey top, do you have Yasuo?".
