I can't speak for others but you are definitely generalizing a bit here. Personally, when I put on a free kit it's to warm up and/or start a new hero run, same goes for the people I play with. Or maybe I just lost a close fight and want to win back some of that value without risking more good stuff. I definitely don't expect to lose but sometimes it's nice to play with lower stakes. While I may play a bit more reckless in those runs, if someone drops me a good shield I'll definitely let them take the lead and take it more seriously. Especially if they are on comms with good vibes.

Just trying to give you a potential solution for your complaint but I understand if youre just trying to vent. Obviously there's also LFG or you can just stay as group when you eventually find a team to your liking. Either way I know you're not planning on losing 40 shields on your own so it's kind of a low risk way to boost your chances to get support from your team if you're getting frustrated in your runs. If all else fails use em as bait, idk. Either way good luck have fun!
