If they removed Gauntlet, they should remove Ranked Battle Royale for the same reason. Matchmaking is fatally slow; even when a match is found, several players drop out, resulting in a delay of over 120ms every time.
Instead of focusing on things like Rapid Royale and the competitive scene, which have unclear demand, they should fix the existing problems in REDSEC.
Did you delete it because you wanted to show off your Rapid Royal? Or did they think 3 modes were too many, so they compared Battle Royale and Gauntlet and removed the one with fewer players?
Did they remove the gauntlet because they couldn't fix the fact that the Interdictor could kill in one shot regardless of whether the target had armor or which body part it was targeting?
