I played a few games yesterday. My positioning has not always been the best and I often put myself in a bad spot to try and flank. With the changes to the damage model, my bad positioning mattered much less. I did a bunch more killing than I normally would have because people could not land enough shots to kill before I could crouch or prone into cover and heal quickly while playing as a medic. I also played a bit of Recon with the Krag and scored a number of kills that I likely would not have prior to 5.2.
EDIT: I forgot to mention the spotting. It also gained me some kills I would not have otherwise.
