Please, bring back FFA! 
I loved the mode too, but towards the end queue times rose, and throughout there were problems of consistent match-making. ie. games with bronze and masters players in the same game. I think both of those result from a smaller player base. Any ideas on how to get more people excited about the mode?
would probably still have more people playing than archon mode.
maybe have a hidden MMR that goes with it as well, so you’re at least matched with people of similar MMR.
but ranked FFA might be fun too…
Bring back FFA take off archon. That would be a move
