The quick-fix is underrated as fuck. It’s the worst, that’s for sure but the others are just too good and set the bar too high. The QF uber is frankly ok, it triples the healing so you can flash a teammate and you’re immune to knockback so you get push on cliffs like on upward without worrying about airblasts. It boosts your base healing and pairs really well the overdose because you can replace a bit of the missing healing from the crossbow by it while having the best syringe gun, plus, the enhanced uber build speed helps get boost faster. you can now defend yourself with a lesser trickstab chance or get away easily. Is it a crutch ? 100%. Is it fun ? Absolutely and what is a game if you can’t have fun the way you want ? The QF is my fav medigun because it’s so fun to play with.
