I think the cost(200mp) of RE is not because of it's combat stat.
It's because of...
1. USF don't need to build RE if original one is alive. - Thanks to Vehicle crew
2. USF weapon rack can spike RE's combat efficiency. So if it is cheaper, we will again see RE spam.
The stuka is fantastic for displacing/destroying team weapons, and punishing extremely static play
That's whole point of the rocket arty (If "zu fuss" means walking stuka), the problem with walking stuka in 1v1 is that it requires back-tech. Which is very painful with limited m.p. in mid-late game.
We used to see around 1 walking stuka even in 1v1 when 2tier was dominant.
Game Meta wise:
We are living in a world of 4inf + (mg) + 2at + 1 armed vehicle -> Tank era.
Sov & WM's tier are very suitable for the meta, while others are not.
OKW: AA half is very tricky & risky to play.
USF: Needs to back tech for AT
UKF: AEC's anti-inf sucks + no snare for mainline inf.
Why pick WM over OKW:
1. Main reason: OKW is next to weakest(OBVIOUSLY UKF) faction in 1v1 ATM.
2. WM's weakest time is right before they get all the tools(mg+222+pak). But most top players can pass that time w/o significant lose. After that, they are very tough faction with all the proper tool to counter enemy with proper skill(which all of the players from the Tourney have)
Why OKW is weak?
1. Rak nerf played important role. But I won't say we need to get back to invisible rak. It's toooooo OP.
2. volks aren't that strong against almost all. It just does it's role. But not a game-changer. That's why people go for Obser or pf for these days.
3. Since 2tier isn't major anymore; AA half is good but very tricky + risky unit to play with. Same goes for AA half from USF.
4. P4J can't dominate over t34-85. And 7cons are more mp efficiency than volks --> Very weak vs. Soviet.
Why pick Sov over USF:
1. Soviet is the strongest(IMHO) faction ATM with man power efficiency of 7-man-conscript.
2. They along with WM has all the right tool with them. Especially because 1tier is not the major tactic for now. And 120 & t34-85 is very viable unit.
3. When it gets to the late game, they both have rocket arti as a stock unit. So player can use it to wipe squad or destory at/mg.
I won't say USF is weak at the moment. But the faction does require a lot of skillful play to gain best of it. Such as controling 2+ armed vehicle... etc. And if they don't get advantage at early-mid game, it gets really tough for the faction to comeback. Need backtech for AT; sherman won't help that much when you are loosing etc. So... Overall, Soviet is more safer option to pick.
No rocket arti w/o commander.
UKF:
meme faction.
At least give snare to Tommies.
