Dat strawman. How about you actually read what people are actually saying, hmmm? A molotov, when it connects successfully, very often killing at minimum one german model instantly, ripping 25% of the dps of that unit, usually forcing a retreat. People feel that it would be better if molotovs did more DOT than crits, turning them into tools of area denial.
I have no idea what your second sentence is even saying since it's worded so poorly. A maxim has six men available to man a piece of equipment that can surpress/pin any other infantry, and one rifle nade hardly ever kills enough men for the mg to no longer be useful.
Holy smokes, a 60 muni upgrade makes a unit way more effective against a fresh unupgraged unit, no shit. Also to significantly drop the dps of a ppsh con squad, you need to kill a minimum of 4 models, but other than that, I don't consider cons to be nearly as big of an issue as others here think they are, since their dps has been nerfed already.
So, lets quickly recap your post:
Soviet mp and fuel upgrade that needs muni to use and is easily dodged is bad, because it might instantly kill one model and might kill more if you happen to be AFK to move out of fire(because not everyone knows that standing in fire=bad).
German muni only upgrade is good, because its an upgrade and should be good.
Don't you see a lil bias here?
And to drop significantly DPS of LMG grens youneed to kill 3 models and still more then 50% of the dps will remain.
Cons and grens are two most balanced units in game, their abilities and upgrades as well except pointless disparity between AT nade and pfaust.
