To be fair, IW's hit detection improved over the year and weapon balance changed several times before they got it right. WW II is only a few weeks old so it's still fresh and needs feedback for them to make changes.

• I can still find NV4/KBAR tryhards in every lobby. They were nerfed slightly but they're still the most versatile ARs. I try to avoid using them.
• HVR is still one of the worst SMGs. It's definitely viable but when the MacTav and Karma exist, it's hard to justify using it.

Then there's the changes they made:

• RAW was nerfed twice, Titan was buffed twice. The RAW was fine. :(
• The Volk was very strong at launch, got nerfed hard, then buffed again.
• VPR wasn't great at launch, got a SUPER MEGA BUFF and was very OP, then was brought back to something more in line
• Type 2 was meh at launch but got a fire rate buff and now it's great
• R3K was pretty crap at launch, but got buffed a few times and now it's very good
