Still managable? Maybe if 1vs1 with bandage and full health if they are not the military one, at least in preavious patch if you run away they can't hit you, now they have 15 meters arms...it took me 8/10 hit with a pickaxe to kill one, at least they should take some sort of damage after hits, lose an arm or a leg for example, that slow them down or made them less strong..

So we had strong zombie that could see you from kilometers can run just a littel slower than you can pass through walls and doors, that can't climb stairs only way to save yourself if you don't have a gun or the grate fire axe, now they can hit you while running they can clim up to first floor and half of second one can hit you also if they are aiming in an other direction. So beeing the fight pretty bugged, aim to the head you suggest as if it's possible with this super speed and teletrasporting zombies, whot are we supposed to do? Just spawned you run in a city if there are no zombie all is looted if there are zombie you can't fight you can't run away you can't hide or climb stairs to save yourself.... this zombies are too much "world war z" but if the fighting and their physics is not fixed they should be much more "the walking (not running) death".
