I don't want the kind of tank maps we've had in RO and DH. Most of them are pretty much pure tank battles with ridiculous amounts of heavy and uncommon vehicles. Then you have the ones that only have AT soldiers and snipers for infantry roles, which - while somewhat understandable in terms of expectations of gameplay - are rather pointless to have on a map made up mostly of armored vehicles.
Those maps were inherently strange, anyway. Tanks going in en masse to seize towns and other objectives over long range from other tanks, with no regular infantry to speak of. Large combined arms maps can be fun, but you have to limit the amount of tanks active at a time to ensure that the infantry can have some fun too.
I'm personally not a huge fan of Gumrak as it is right now. If made into a combined arms map with a bit more cover in the objective zones, it'd be great. Many tank engagements involved infantry in some capacity or another, especially if they involved the seizure of urban areas. Since Gumrak is somewhat reminiscent of Arad to me anyway (The layout is somewhat similar), I think infantry support for the armor would spice up the battles on the map.
