Nah, I think this is actually worse in many ways. Fighting a Viscous who has enhanced rapid recharge who can spam slime punch nearly once every second isn’t a good or fun learning experience.

It’s ARAM chaos mode.

I think it’s mostly going to just be an arcadey mode. Not every hero is well suited, the items are balanced around the standard 6v6 format, and the legendary items are just silly (infinite magazine, piano drop) and that’s fine. I don’t know if I would ever try to get new players to start Deadlock on this mode, it’s not exactly beginner friendly. But it does have the advantage of a lower time commitment, and you can try a hero against real players in a short format, no consequences match mode this way. I think unless Valve sees a sizeable, recurrent player base for this mode they won’t change it much. Or unless someone at Valve is particularly fond of the mode.
