Once you play a few matches it is basically all the same for 2vs2 matches.

Game needs to randomize resources types and have more locations for Geologists (Engineers).

Player startup location should be randomized as well. Not always top vs bottom.
Not always starting at the exact same location.

You always start at the center. You could start closer to a shore, or near forest. Add something so that gameplay and each match is a little bit different.
Otherwise game's get boring fast with like 5 multiplayer maps for 2v2. Other modes don't have more.
