hmm, not sure about that Toxcatl
my personal experience is that a team, an opponent who can bring a lot of friends-supporters, usually has an active manager who 's spending a lot of time in the game, is connected with some T11 fb group and has a deeper knowledge of the game so support % is the less I 'm worry about.
Also another thing is the 80-20 rule (Pareto principle
https://en.wikipedia.org/wiki/Pareto_principle ).
Usually 20% of my friends gives me the 80% of support in games - lol
But I know that, I have many friends which I know that they 're not so active anymore.
