Yes, still they have higher potential to become eSports than 1v1. So it should taken more serious. Positioning and infantry are also important.. you don't always go with all on one side. Example : Lazur Factory the top side is 1v1 contested most of the times. Montherme is build to be a 1v1 and one 2v2. Angermünde is mostly a 1v1 at all 3 stars in early game. Lienne Forest right side is a 1v1 too or a 2v1. You guys should give it some thinking and play 3v3 or 4v4 with your friends and see for yourself.
And also big tanks don't cap you vp's.

Infantry wins you more games than the big tanks since they can be fucked way easier.
