This isn't a new game mode per say, but with the Infernal Dominion event, I got a taste of something amazing: Dominion without gear nor feats. So Ubisoft, please give us the option to play any game mode without gear or feats. The game feels so much more balanced this way; no Bleed + Fear Itself, no Kiai, no Aramusha who has Rock steady for some reason...

It would also make Elimination a lot more fun to play as your opponent wouldn't get revenge in one-on-ones thanks to gear.
