Ah, so you assumed I was being petty against a particular playstyle.

I'm referring to posts I've seen where people are straight up brainstorming which perks to share to mess with others, a lot is aimed at bloodied builds. I'm all for people playing how they want in good spirit, as stated I just left the team and let them keep on since they didnt want to change.

Knowingly negatively impacting other players without any personal benefit on the other hand, that's rude. A medic is supposed to support, destroying your teams most fragile player makes them a poor medic. Most camps have decontamination arches and radaway is more then plentiful, there are better cards for sharing such as making stimpacks more potent, autostim, etc.. Sharing sunkissed is ideal for niche scenarios else your wasting potential.
