Theres unreleased commanders left in old closed betas:
Some old pro-players (who left the community long time ago) were against these commanders in closed betas. I think its time to release that and Ardeness Assault MP maps for everyone in the automatch map pool.
2 of them could be seen on automatch. They weren't released, because they are Tiger Ace release busted. Similar concepts and mechanics have already been implemented and removed from the game. There were other concepts been tested but i think it end up been absorbed by USF/UKF/OKW.
The only "unique" unit would be the commissar. Giving different weapons/abilities to old units is not necessary new content. Giving units/abilities from other factions is not "new" content either.
Urban Assault Doctrine:
-Urban PG: A unit which you could buy armor and put (2x) flamers. What could go wrong. Basically same situation to Riflemen/Penals flamers were.
-Direct resource manipulation has been removed from the game.
-Strategic bombing: UKF basically got it and it has been "reworked" recently.
-Mortar flame barrage. Basically what ISG got or what MHT always had.
Not one step back:
-Reverse soviet industry.
-Resource manipulation again.
-It was basically maxim spam.
-Commissar is the only unique unit we know off which could be implemented, using the same or other mechanics.
Green T34: basically a puma in the skin of a T34. If you like your units been randomly stunned, you would like this. If you think ram is a great mechanic, this would be your unit.
T3485 ace: because we need units coming out freshly with vet 3. Call in tank bundles have been removed from the game.
I would release them, but not for automatch. Custom/AI games are fine with them.
