I'd like to see a plain, relatively featureless open field map. Maybe some very light rolling hills, but on the whole pretty much a clear shot between the two firebases. Maybe two maps, one with rolling hills and one that's more of a plains.
While advanced tactics regarding cover and odd obstacles are good and well and can be quite exciting, every single map in the game is currently built as such, thus making it feel a bit 'forced' as if it's compensating balance-wise for long-ranged weapons being too powerful (or short-ranged weapons being too weak).
So many canon Battletech battles take place on such plain, relatively featureless terrain. There's nothing that showcases the power, majesty, and awe of Mech combat like a good ol' slugfest on an open field of battle.
Actually, this sounds awesome to me. (as plain as it is

)
Once the LT gets some strong disadvantages according mobility (or maybe if it is deactivated on this map) something like this could be pretty playable. It would force peole to stick with fast MASC mechs, fast tanks and combined heavy/assault AMS lances so they are able to survive the constant LRM bombing, but that is nothing I wouldn't play. Actually, since I'm an Owens pilot, I'd like that scenario. Running around at the flanks, rushing in only long enough to kill or disable a LRM Boat that seperated to far from it's team, then turn tail and run for your life

.
ASF would be pretty dangerous too, because you have nowhere wo hide from bombing runs.
To keep this playable the map should be very big, maybe something about 6 x 6 km, to avoid people from beeing killed by LRM and ERPPC the moment they exit one of the hangars/dropships (I would use 3 per team) and to prevent a single AA to reach from one end of the frontline to the other. Some small details should also be added to the map, to prevent it from looking barren and empty, maybe a small wood, 1 or 2 hamlets or farms consisting of only 3 or 4 mech-knee high buildings and a small river flowing from the NE to the SW corner of the map.
This would be beautiful
