Just played a round of Mann Up with randoms, and I got paired with a skilled team.
That said, they were a fucking pain to deal with. I Mediced with the Quick-Fix, and they berated me for not buying the overheal upgrade, not using the Kritz, relying on the QF as a "crutch", reviving them next to giants, relying on my shield too much, and not pocketing them. Isn't it my fucking job to keep people alive? Apparently I didn't do it well enough or in the style I should have. Worst part was that when they criticized my play it was "this Medic" or "he", never addressing me directly. A little common courtesy and speak to me like I'm in the server, please.
God damn never again I don't care if they're skilled I'm only playing with you guys from now on.
