Exactly, see, you made my point for me. RE can do other stuff other than DPS. Same with MG34. It has more pen, a MUCH better vet1 ability that allows it to kill light vehicles and a much wider arc compared to the maxim. But you just want to look at DPS, that's fine. That's why I said, pure DPS comparison to cost is silly if that's all you're looking at.
It's really hard to read your paragraph but it sounds like you're saying after the squad retreats then the mortar just bombards until it dies? I could just move my MG34 if I'm being bombarded. We could theory craft in circles like this all day but it won't get us anywhere.
it vet 1 ability have pathetic damage because its damage. if i remember right incendiary rounds x2 its damage so it bring the MG34 damage to 4 which is normal HMG42 DPS before incendiary rounds, I can't find pen for incendiary rounds ability so can't say much about it. and from my experience that HMG34 incendiary round from HMG34 is scratching M3 scout car. and how often you see HMG team use its abilities, their ability need special reload which breaks the fire. quite useless in most cases. and i don't much see pen differnce when against infantry or any vehicle between the HMG. I actually see more Maxim use sprint than see HMG42 use its incendiary rounds.
yes other HMG the sq will retreat and move away. HMG34 can't really move because it is pin other a sq, if they move the sq get of suppression and keep give vision to mortar. i am not saying only compare its dps, but for HMG team their use is similar and there is up and downs, HMG34 biger arc, slow setup, while maxim more men and quicker setup so those can cancel each other.
anyway i am done.
