Ability hotkeys get knocked aside on the command card by other, optional doctrine abilities (or even abilities gained via upgrades?). This changes their hotkey for the rest of the game. Confusing and not fun.
For example, Wraithblades have their taunting charge abilit on W by default but with Wraithknight Taldeer’s trait that goes to E and W will become the hotkey for the Taldeer stasis trait. It should be the other way around, the newly gained and only optional ability should go in line to the next available slot next to a default ability. This’d make hotkeys easier to memorise as well.
