The problem isn't the game, it's you. Stop crying, watch some twitch/youtube replays and learn to use different strategies against different opponents/commanders.
[Indirect fire]
You can't beat land mattress? Don't blob! Not your infantry, not your crew served, not your tanks. Allies have to deal with mortars, ISG's, Werfers and Walking Stukas. Don't tell me you can't deal with a land mattress.
[Emplacements]
Can't beat emplacements? Build stugs/pak40s/jagdpanzer/raketen and target ground. Don't like this option? Find your own stategies because there are many more. Allies have to deal with mg nests, Pak 43s, and LEFH emplacements all while fighting against the best tanks in-game. Don't tell me you can't deal with an emplacement
We, the community, are also willing to give you advice on how to beat them, but the constant forum crying to nerf this or that faction is ridiculous. There is a counter to everything in game, it is YOUR responsibility to find that counter. This isn't rocket surgery, it's a simple game of digital chess.
PS - you won't win every game.
