But I also play as a pybro (aka helpful pyro) spychecking and extinguishing with a s.flamethrower/scorch shot/homewrecker if I've got a solid engie or two on my team. I'd use a degreasser more if I could get a strange one.
Is the pomson really that good post-nerf? Whenever I face a pomson engie I always feel he could get more damage on me with the stock shotgun (or FJ if he's spamming minis).
Nobody is really a bad person for using minis, but you probably shouldn't feel accomplishment for all the scouts you're autokilling. It's really on valve to nerf it, and I'm sure they will eventually. But like all valve things, it happens in valve time. I knew they would nerf the equalizer one day but it lasted a lot longer than I expected.
