I say the Allies should get a stationary aircraft carrier instead of an airfield to add a little of spice to the map. Give the Carrier a Martlet and a few Swordfishes
Desert Rose is one of my favorite maps, a real chance to go into battle on my steed, a Crusader. I do think that the bottom segment should be completely removed. Don't make any other changes besides giving the Brits an airfield as well. Chop off the bottom and slide the whole map down until the water covers around half of the map.
A jeep is a good idea, great last ditch suicide vehicle. It can take out any tank, maybe not a KT or IS-2, with a good run up
To give the ships something useful to do, why not simply add a flag in the sea, like Point Luck and Point Charlie in the Mdiway map?
Historically this could represent how the side controlling the sea not only got potential naval artillery support, but could also threaten to make landings in the enemy rear.
The two flags in the south, allies have only a bridge to approach them, while axis have a bridge AND can simply drive around the lake to the south. Not even a bottleneck guarded by an AT-gun there. Isn't this like very unfair?
Give British a second bridge at the very least.
