Better System for Hotkeys

[CollinHerber]

Description

Right now some hotkeys get a bit long and don't look good in their place.

Need to come up with some way to counter this

There's no real way to combat this with just a 1-character space allotted in the UI. It might be best to make it 1, 2, 3 unconditionally, unless it's another number (0-9) or another single letter (A-Z).
Default right now is 1-2-3, which is very awkward in gameplay but that means a player has to choose to make it something else "unintended".
Alternatively, we could show hotkey on the tooltip, i.e.

(Press Hotkey to use)
Fireball
8 second cooldown
