They have been. It's largely indirect, but there have been plentiful boosts to survivability none-the-less.
Biggest points:
- Squad spacing has been improved
- The Ostheer half-track now vets passively
- Medkits made vastly more viable
USF nerfs against grens
- Riflemen have less vet 3 survivability
- Riflemen only have one LMG slot
- Mortar fixed
Soviet nerfs against grens
- T70 less wipey
- Quad less suppressey
Brit nerfs against grens
- Only 1 LMG per tommy squad
And potentially some other stuff I'm too tired to dig up or debate.
Anywho, if you want direct buffs then make a strong and well-presented argument with evidence and logic. There are seemingly a million people posting completely substanceless crap about one little thing or another on these forums. It takes a lot of effort to stand out from the overwhelming noise and get people properly on-board.
Brit only 1 mg? Ok they die
