I don't agree with you. The cover system may have problems, but it's there and it works. It needs bugfixing and tweaks though. The melee through wall has been adressed, except on some places and props. You're not supposed to shoot through walls, this must be a bug. Hmm, watch out for the "open" walls, like windows and the like, they ARE open on the upper half, so LOS enabled and cover disabled! There are 3 height levels of cover, and several props take that into account. You can crawl under a bed for example. There may be a problem with the damage localisation, i'll have to test that again when i'm home. Some people argued about that on JAF forum.
