I always play as the medic. I dunno' what "The Kritz" is though. An unlockable? I only know about ubercharging to make guys invincible, I usually use it on something that would take a lot of hits like the HW guy.
I heal anyone that's injured and scan my crosshair over my whole team really fast all the time so that I can find someone who isn't at full health. People on fire are especially important, because I've been lit on fire too (in the game) and I know it sucks.
I might give HW guys a health boost but I rarely stay on them, or anybody, unless they're moving forward to attack, or there's nobody around to heal.
