On "RO1" I found infantry only usually boring same old stuff all over again which was not helped by some of those very small (8 vs 8) custom maps being played on 50 servers which was just a giant frag, smg, and artillery fest.
I really liked combined arms maps such as RO-Pavlov's house, RO-Gorlitz,RO-Kreigstadt, RO-Pariserplatz, RO-those AHZ maps, DH-Stoumount, and DH-Stavelot. I think most people would agree that combined arms maps are probably the best type of map which makes the majority of players happy although there is one flaw on some of these bigger maps that would really add to the map the spawn areas. I think you should be able to spawn in areas that are under your teams control ( in captured obj) and the ability to ride on tanks would help as well and not have or encourage ill usage of HTs on maps.
Tank only maps are awesome if you are a tank fan which a good number of Ro players are or perhaps were as was seen for example on RO-Orel which was a classic and was played on many servers since it came-out and probably has the most variance of any map except perhaps RO-Arad (lol). It was quite fun to get on and coordinate attacks over the microphone (several years ago anyway) having your team keep the tanks together in little battle groups, frustrate the enemy by blowing their bridges as well as taking them out from 800-1000 meters and pushing them back across their side of the river as you mop up any stragglers and cap the last cap zone.
My only complaint about these large tank maps is the lack of realistic tanking in RO1 which detracted from the experience anyone who has played RO-Debrecen (or a similar tank map) with the Armored Beasts mod knows how awesome tanking can be. I loved using the Panther and blasting the IS-2 to shreds at long range with a nice clean hit on the weakly armored turret front and mantlet something that was not modeled in the stock version of RO.
