Am I really gimping myself by not taking Regen shots in clash?

When I play Hunt I'm usually stuck playing clash because it's the only version of the game the guys I play with like to do. I'm a crochety Hunt purist, so it's not my cup of tea but it is what it is when you have a reliable group to play with you know?

My one friend rags on me so the time saying that I get in desperate situations a lot because I don't use Regen and recovery shots, and literally everyone else does so I'm putting myself and our team at a disadvantage and I should just do it. But on principal I just can't bring myself to take them because I just find them lame, like they go against the very concept of attrition that made fighting in Hunt interesting. Like no matter what you can only take so many hits before you go down and that going down meant something, and it balanced well against ammo being (usually) so limited.

But does everyone else really take them to bounty clash, and I just need to suck it up and just accept the new meta so that I'm not a drag on my team?
