No need to be so personal here Mr top 20s rank. We get that you're a hot shot now since you're part of the community team but no need to be an elitist ass and let all of this go to your head thinking that you're a cut above the rest.
I don't care about ranks and never have, that's why I'm normally never showing it off nor do I ask others for their playercard, but to me saying Feuersturm's abilities/units are bad (with the exception of incendiary ammo and Opel Blitz) is the equivalent of calling the new Stormtroopers bad. It's quite clearly a learn to play issue. I only mentioned my rank because I can't be bothered to write an entire essay about why Feuersturm is good when I can just say that it is good because I know so from personal experience winning the vast majority of matches I use it, and I think a high rank does give such a personal opinion more weight. These are cases where the stats and numbers simply can't tell the picture.
I honestly have no other way of describing Vipper's arguments there. I wouldn't even know where to start. He thinks the Hetzer is bad because it can get killed by a T-70? Yeah and a KV-8 can also get killed by a Panzer IV, but that doesn't mean it isn't a great unit. 1 flamer doesn't have a high enough impact? Well yes, that's why the usual strat with Feuersturm is to open with double Sturmpioneers exactly to get that high impact. UKF/USF infantry and Penals can just retreat if MP40 Volks manage to get close? Well yeah forcing off enemy infantry is kinda their purpose. The psychological effect of having an AOE grenade when people are used to a flame grenade should not be dignified with an answer? I couldn't even tell you how many times I've thrown the Model 40 grenade into infantry with the enemy player thinking they can just walk through it because they thought it was a flame nade.
These arguments are the same as those made by players who state MP40 Stormtroopers aren't good after running them straight into the enemy in a frontal charge, for example.
