If the Rank mode going to be team based on single
What I liked about the era of when I was a Pro on MV, was 1v1, FFA and clanwars
I think the rankings should focus around that, for those who prefer 1v1s, and does who dominate free for alls
Clan wars should be the standard for ranked games but, you'll have to acknowledge a lot of pro players prefer the 1v1 and ffa especially to outskill with sniping match ups.
