I'd think that losing units- and as a direct result losing ground and therefore resources in both income and invested- means you might be able to unlock CP abilities faster, but not have the resources to use them, and more importantly not have more units to accompany said new abilities. I'm not going to sacrifice my vet3 Grenadiers just so I can call in an airstrike a bit sooner for the same munitions cost. Stock units will always be more valuable than doctrinal unlocks, simply because you need units in general to maintain resource and ultimately win a match.

Losing units mean no units to take or defend the sectors you have. Fewer sectors mean fewer resources...on top of the obvious tactical disadvantages. Good luck rushing Tiger if the enemy can churn out SU-85s faster than you can churn out Pioniers.

That's not going to happen if you just churn out units to acquire CP but lose the map in the process. Units take time and manpower to train, on top of upgrades and teching, which take up slot queues.

Players do get XP when things are lost, but there's far more to the game than that. Most players would rather gain XP while killing off opponent's units, than the other way around. Simply because you're not winning when the latter occurs. No units = XP but no map and no resources, meaning no Tiger to call in. Hardly being rewarded for poor play.

The limitation really just forced from one popular meta to making another, which I'm sure was the intention. That they didn't limit Churchills or KV-1s pretty much exemplifies this being flawed logic, but what the hell it changes the game lelic style, right?

All doctrinal units had clear differences in advantages compared to stock units, and almost all of them are either more expensive as compensation, or deliberately sucky but comes earlier and cheaper. Tigers compared to Panthers etc are no different.

If they ninja-changed the game so you could in fact call in unlimited heavies besides King Tiger and Tiger Ace, I'm 99% sure no one would ever notice...nor ever take advantage of it. And before you say "well what's the point then?" I cite their removal of duplicate bulletins: the point is just design decision, nothing more.

USF:

Air Defense Company
1- Field Defenses
2- Anti-Aircraft Positions: Fighting Positions can be upgraded with Quad .50 for improved anti-infantry and suppression for 90 munitions, or 37mm for improved penetration. Both upgrades replace garrison slots, but become more durable.
3- Officer Rally: Officer squads can halt the retreat of friendly units within its radius. Has long cooldown, but each squad has its own separate ability cooldown.
4- Air Superiority: Global ability, while active frontline sectors will be strafed by P-47s; highly effective against enemy infantry and light vehicles, but inflicts little damage against tanks.
5- Antitank Overwatch: Off-map 90mm batteries barrage enemy vehicles over selected friendly sector; APC shells have low AOE, but highly effective against vehicles.

Signals Company
1- I&R Pathfinders
2- Mortar Halftrack

They're called loot points, not supply, and not "coins".

It's probably just a bonus thing like BF4's double XP weekend.

Personally I liek it, especially if it was predictable like every weekend.

Recency effect, Relic loves it lots.
