I like variety. To me it seems as if we have far more "ambush" type terrain in the MA than anything else. It would be nice to have a Kursk style of terrain from time to time. A few trees with wide open space, with some rolling hills with a few ravines to use for cover and movement.
With the new tank reticules and control interface coming our way in the next version, I think it is going to force more movement in the ground game regardless (which is good, imo). Cover wont be as highly sought after.
HTC had changed the maps a bit and reduced the number of random mounds to hide behind (a 12-18 mos ago?), and then changed them back. I think there is a happy medium somewhere. Currently, imo, there seems to be too much of everything. Too many trees, hedges, mounds, etc. Every map seems to be too similar.
