Hotkey sets?
Im not sure if this really matters but here it is. Can we put in the game hotkey sets? Sort of like item sets for certain champs, but for hotkeys.
Example:  's hook might be wanted to be put on normal cast. His other abilities might be wanted to put on quick cast.
So different champs have different abilities that might want to be normal casted/quick casted. So instead of changing hotkeys at the start of every match to fit the champ that is being played, there are hotkey sets that change hotkeys for you. Same concept as item sets. Just an idea :)
