In my opinion the infected move slighly too fast but that is not really an issue. The distance that they can see you from is too far, way too far plus the infected can see through buildings as well as walk through them but I'm sure this is due to be fixed. Also they now cause bleeding after 1-2 hits which is a little frustrating, maybe 3-4 hits would be better? I find I am having to bandage every 5 mins and am quickly running out of rags. My crew and I have been considring farming new spawns for their t-shirts just to get more rags and that surley should not be how the game is played. Respawning is okay as long as it's not in view of the player, I am seeing infected just appear in front of me now which is kind of annoying.
