-Size of Map is too small( my opinion) for a 2v2 map.If ffa style is selected then im ok with it but for 2on2 its too small
-Some doodads like the staircases need to be fixed cause they really look like hovering
-I didnt like the tide guardians at the middle of the map.My opinion is that they are just stalling the player's units and give no gold at all...
-About the so coming expansion:
-Hero taverns.....Where too put? no space left...
-Nothing more will make it better.A remake with largest scale (160x160) will be better for both you (to add more things ) and for the players who will use them
