How is decrewing the B4 equal to losing it?
Losing the B4 means you're out 600 manpower if you were ever to rebuild it, not to mention the time it takes to save up that amount/actually build the gun.
Decrewing the B4 costs you a whopping 60 manpower assuming you recrew it with Cons which should happen 100% of the time. That's literally ONE TENTH the cost of having to build a new one. And I'm pretty sure the firing cooldown resets if you recrew it (although maybe they've finally fixed this bug by now? works with all howis if I remember correctly).
The fact of the matter is that if you do not have the only reliable answer (stuka dive bomb) to the B4, you're pretty much screwed. I'm not saying you WILL lose to game... but it is going to be extraordinarily difficult and certainly not in your favor. This pigeonholes Axis into having a Stuka dive bomb as part of their team composition because other off-maps will not guarantee a fully destroyed B4. It is just poor design when one faction is majorly pushed into countering a doctrinal unit with a doctrinal ability (at least in my opinion - the same could be said about Mark/T34/85s/Is-2s being preferable to T34/76s or even Su85s when having to fight Tigers - it just isn't a fight that the non-doctrinal Soviet armor can keep up in). Sure the Jaeger Armor commander is one of my favorites because I like the 251 mines and spotting scopes, but do I want to play that commander every. single. damn. time. that there is a B4 in the Soviet load out and Shocks show up on the field? Nope.
Or the fact that a vet 3 B4 can literally one-shot a King Tiger. Completely insane for one unit to be able to do that much damage with no way of the opponent reacting to it.
You don't use B4 often, do you?
It's not about manpower.
If I lose B-4 in 5-10min since build it's not bid deal.
But if I lose it around 40' of the game with vet 2/3 I'm done. I have nothing to stop enemy's blob.
I'm losing 50% rotation which makes my B-4 useless against player who knows about rotation speed, I have KV-1 vs Jadgpanzer/Panther/King Tiger.
Enemy knows I don't have vetted B-4 and in fact he can risk more.
Vetting to 2-3 again takes about 15mins (of course I can vet in 4mins but that's very unlikely), which means I won't get vet 3 again.
Loss of a vet 3 B-4 is like loss of a Tiger and replace it with Pz IV.
Just recently I had agame with friend vs OKW&OST.
We were 70 vs 400 VP. When my B-4 got vet 1.
From that point we pushed them back to 70 vs 150.
I lost my vetted crew around 60 vs 40 and since that moment they ve pushed us really heavily.
We won only because of VPs left.
By the way, OST guy had one doctrine with stuka yet he was complaining about B4 (he did not take this doctrine).
What's more, when you see recon plane it's obvious that Im looking for a target but most of the time it's too much to move units until plane is gone...
Taking main points with huge blob is also very smart vs B4...
So whose fault is that? B-4? No. It's my enemies fault that they are doing what I excatly want from them.
