Lol depends how many players really
There are some GREAT doctrines that support you and your teammates. Assault Support Doctrine is currently my favorite.
Close Air Support was neutered a bit by making enemy infantry able to avoid being strafed (good old days where I selected a circled area and any units inside became strafe targets). Definitely had better days before you had to choose the attack run.
Elite troops seems more of a 1v1 type of doctrine. Its been nerfed hard since its creation, some people still use it. SOME.
Mech Assault is a good doctrine, before Western Fronts it was all I used. Just tier 2 then wait for the tiger.
Tiger's are pretty lame though, in team games why spend all that gas on a slow moving target (that can't even rotate its main gun fast enough to catch the 3 Jackson tank destroyer's flanking it) when you can get 2 or 3 Panzer4's with some Pak40's? Much better IMO.
Better force projection.
