If there are customized key bindings using Shift or Ctrl modifiers it may happen that an ability gets assigned to a hotkey unintentionally.

 

Example:

1) Customize key bindings and define CTRL-N for "Next Character"

2) Hover the cursor over an ability

3) Switch to the next character using the key CTRL-N

 

Observation:

The ability is assigned to the Hotkey "LeftCtrl "

 

Expected:

The character shall be switched to the next character without assigning an ability to a hotkey.

 

Suggestion:

I would suggest to make the hotkey assignment more explicit using an explicit key to initiate Assignment-Mode. While in Assignment-Mode the UI shall indicate it clearly and allow to switch characters and assign hotkeys to abilities. Use the same explicit key to leave the Assignment-Mode

Just in case in wasn't already considered - the player can also bind the Alt key as a hotkey. So when it happens by pressing Alt the game will assume we are using the ability and also switches to/out scounting mode at the same time.
