The Militia’s “Back to Work” ability hotkey seems to be missing in the hotkey options
The “Sundering Blades” research hotkey seems to be missing too
The Shaman’s “Purge” ability hotkey is missing as well
The Sacrifical Pit’s “Sacrifice” ability is missing, only the one on the acolyte can be changed
The Crypt Lord’s beetle “Burrow” ability is not the same as the Crypt Fiend’s burrow, and is unbindable
The Necromancer’s “Unholy Frenzy” is bindable in the hotkey options but stays on “U” no matter what you bind it to
The warden’s Avatar’s “Spirit of Vengeance” is ubindable (not very important since it’s autocast)
Key bindings are not available for Neutral buildings aside from the tavern (Mercenary camps, Goblin laboratory, Goblin Shipyard, Dragon Roosts) even though they are used in some melee and campaign maps. Mercenary camps and the goblin lab are particularly important since they’re used very often.
