played some last night. 80% are level 70 or more players. can't live in all that bombing and airplane fire. I guess they are letting retail players in on the servers too instead of just newly joined steam players.
That is correct. Thin walls, like wooden walls, allow bullet penetration with most guns. That has been there since Call of Duty 4.Though I think many new players are calling a hack incorrectly on Bullet penetration (you can shoot though walls in this game right?).
Sounds like Bad Company 2 will address most of your concerns here... just sayin'.
