Scott is very good unit, no doubt but in 1v1 Scott may be your third or fourth unit. You can't go for Scott as first one so it can be used only in late game.
What's more, one bad move into Volks areound the corner and it's dead, like all USF' vehicles.
Priest is powerful, I was able to kill even Elephnat with 3 Priests but it has space only in team games. In 1v1 it's a waste of resources. Too much RNG involved, after 1 shell very easy to dodge, very hard to catch moving blob. And like I said, no place for Priest in 1v1. Stuka does better than Priest. So do Katy and PzWerfer.
Priest is only good at killing OKW's trucks.
75 howitzer? Really? You are saying that 75 is good but leig is a pudding? They are quite similar. I find both of them useful tho. Leave it behind lines and you will get 20-40 kills in 30min even without touching it.
Now I have a questions for you.
What is best non-doc mortar? Yes, axis' one.
What is best mobile mortar? Yes, axis' 251.
Which unit has best barrage ability? Yes, axis' Stuka zu fuss.
So please, stop saying that Allies have better indirect. 120 or B4, yes they are better than OST mortar or on map arty but on the other hand OST and OKW jave best non-doc mortar, nad 251s.
The 120mm Mortar, Priest, 152 Howitzer, B4, ect. These heavy artillery pieces are something that OKW has nothing comparable to, and Ostheer's 105 LefH is literal garbage, it's shell only does sligtly more damage than a 120mm mortar shell.
The best non-doc mortar is not the axis one, it has a higher ROF but is less accurate and the precision shot that the Soviet mortar has can easily be used to wipe infantry squads/enemy mortars, the best mobile mortar is axis I'll give you that, and the best barrage ability is definitely not the Stuka Zu Fuss
If we are talking fuel costing barrage units, the priest wins by just not costing as much. A priest is a call in, and it doesn't fuck up your teching like a Stuka does. And before you say it, yes the Stuka Zu Fuss is good, but it's expensive as shit and OKW should have howitzers/other indirect fire units that don't cost fuel.
You say that you think it's stupid OKW has such a man power float, well why not give OKW something to spend MP on like a non-doctrine howitzer of some sort?
