Actually, that could give some use to the quick fix. Heal a scout or a RJing soldier with it to get around faster, then switch to the stock/kritzkrieg. And if the uber is shared, the QF can charge your uber faster before switching using the uber/kritz.
Scout: Pistol + any drink Soldier: shotgun + banner/gunboats Pyro: shotgun/detonator + flares/detonator Demo: stickies + shield or jumper Heavy: ok maybe not much of a benefit. steakvich AND sandvich for double-healing abilities i guess? Engie: pistol/short circuit + wrangler Medic: UBER + KRITZ OH GOD YES Sniper: smg + jarate Spy: uh... sapper and red-tape. sure.
My opinion is objective fact. If you disagree, well, you're wrong.
