So far my only complaints are the fact that medics are pretty much useless, because now you don't see the icons of people who died (you have to specifically request to be revived now, which pretty much nobody does). So during my few hour medical career, I only revived a handful of people.
Secondly full on automatic weapons are such joykill, the bolt action rifles feel great, they sound great, have great recoil and most importantly they feel powerful. Yet most people still choose to use full automatic guns and most battles in closer range just boil down to people blindly spraying in hopes of killing their target.
