Can confirm this still happens very often. Gold combo orb seems to trigger it more often, but will happen regardless of colored orb. Please look into this as it's been a thing for years.
For anyone curious, video demonstration of how Command Keys now work suffice.
Aside: I found two instances of when it can still be used as an improvement to regular hot-keying, but the activation is too inconsistent to warrant using it in success…
The commands are broken and just straight up clunky. Why did they think this was a good idea? Also, the loss of 15% final damage hurts this class quite a bit considering final form is rarely used for any of the bosses that matter.
