In 2v2, there are some players who have a habit of teleporting right up at the middle of the map when both your players are further back, this means you are unable to even use your half of the map, it's obviously not fair.
This rule is the best solution to that, yes we understand some people won't like that and think mini-bng is lame, but the truth is gives you more options and tactics to use in BnG making it more fun if you actually enjoy BnG and don't get stuck up about who thinks what's lame...
I think i'll enjoy it, if 2 people wanna hide close to each other, let them lol, maybe against all odds they just want romance...
