4 paragraph to show yourself have no understanding that they are two different types of unit which serve completely different purpose. You don't have to hold the line when using stuka, priest and katyusha etc.Any player can tell the difference between them and scott which have different mechanism to work in the game and that's why USF have priest. But they should not be locked behind doctrine.
I swear we have had this discussion before...
They are not meant to have everything non doc. It would break balance and REMOVE diversity if ANY faction had a non doc howitzer. As is now many team games devolve into a grind and battle of Artillery supremacy. If USF has a hard point they have a number of great tools. They have 3 indirect fire options (mortar, pak howi, M8) as well as an off map barrage on the major. Learn to use the tools you have, especially when they are as good as they are instead of whining about what you don't have.
The only faction with a similar number of indirect fire options are the Soviet (because of the zis and su76) brits have all of 2, wehr have 2 and okw have 2. If any faction needs nondoc rocket arty it's the bloody brits who only have an immobile pit and unreliable base howitzer. But instead you are whining about the faction tied with most options because of a tool in a faction with half as many choices.
Ost vehicles smoke is BEHIND A DOCTRINE but usf has it on many of their tanks
All other factions need a doctrine to call in off map arty, but usf has it stock.
All other factions need a doctrine to heal their armour without engineers, but usf has it stock
No other faction getsfree squads, except usf
No other faction has stock smoke on ANY of their infantry, but usf gets it on all the squads they don't even have to spend time building!
No other faction can increase the build speed of their units, but usf has that ability on their free unit!
If another faction wants recon they can call a strike from they need a doctrine but usf gets it on a free squad!
Wuit whining about what you don't have and learn to use what you do
All factions are different. I have faith that given your hard on for USF, given the time you'll figure out how to use them.
