First of all this thread has not much to do with Strategy discussion: I would suggest to move this thread to Help or General section.
Aside from that, what kind of map are you looking for? What criteria must be filled in your eyes?
- Simply go to -> https://www.warlight.net/Maps
and align maps according to territory size and look similar territory sized maps. For example 120 up to 220 would be good place to look 2v2 maps. Other than that, it comes down to specific settings and personal opinions what is best 2v2 map.
