New idea - add this (read my post what i mean) to match loading screen.
I have an idea. Is it possible to add icons of champ abilities (I mean Q W E R ) to loading screen (when your match is loading)? And if you'll mouseover some ability icon, label with basic facts about that ability will appear. You can better prepare yourself for fight and during that loading (sometimes it's extremly boring) you can study champ abilities.
I know, PRO players don't need that so this idea can be used only in blind picks games (or maybe in draft unraked games too).
