Of course I’m not suggesting that you should fire the uber only when the PATIENT is dying, I just mean that it infuriates me when a Sentry may be round the corner, and the Engineer who owns it is at the end of the corridor. He peppers me with shots that don’t even do 10 damage, and the Ubercharge goes up.

Seriously, you could at least wait until we’re in the Sentry’s line of sight to squeeze more time out of it. That said, of course the Medic’s survival is top priority, but when I’m the Medic, I generally wait until I’m at below 50% before activating it in self defense. As long as there’s no ambushing Pyro or Scout, a competent patient should be able to protect me from any other opposition anyway.
