I love to play Lend-Lease Tactics.
Access to both M5 HT and medium tanks through call-ins, dat fancy pintle MG on M4C Sherman, y'know... MG weapon team even if I choose to tech T1.
Unfortunately, when there are at least one OKW player, I forced to play only with 4 abilities. If base defence flaks don't shoot my fuel airdrop plane, then T4 will do.
So factions, that heavily rely on call-ins would be punished while others will roflstomp (even more) in the late game.
As a soviet 4v4 player (mostly) I say - no, thanks. At least not unless there are non-doctrinal heavy armor alternative. Like KV-85.
Most of soviet units sound unnatural and ugly in both english and russian versions. Nobody talked like that. I'm okay to hear something like this in a game like Red Alert where grotesque takes place (tank factory looks like orthodoxal church?), but for CoH... that is too much. I mean voicing is good, but the phrases itself... I don't buy it.
I usually play 4v4 with my 2 mates as soviet. Recently one of them have bought Urban Defence Tactics. It is such a faceroll. We just take fattest building at the middle of the map (if there any) and pwn everything.
So... what I wanted to say? The point is in teamwork mostly. Faction balance isn't a thing when you are supported by other players.
