dedicated usf main who is constantly under the rank 300 vs the strategy of a guy who won five games of USF in the span of 10 years
I've played vs him, owned him HARD 2 times. Played with him once, he played USF, got owned HARD by barely half a faction (the enemy actually knew who he was and decided to focus me and the 3rd ally hard, Vipper was just camping on the VP spot and doing 0 dmg, spamming Priests). The best thing to do is just ignore, let him talk to himself. The only maps where USF can actually build a mortar and not suffer for the rest of the game are maps like Ettelbruck.
Dense, tight maps.
Those maps, because it's super easy and quick to rotate and help out a teammate because in the end, USF mortar is just bad at doing damage and does not fit into any competitive build for any game mode.
If you go mortar vs OKW, you'll get steamrolled by kubels and spios.
If you go mortar vs OST, then you better pray to God that the OST player will not adapt and still go double MG42. Most good player will just upgrade fast MGs + 222 and push the USF back to base...
And on those dense, tight maps, you'll only be spamming the smoke, 0 bleed, 0 dmg, just smoke usage. If you tech nades early to bypass the shi*stain that is the USF mortar (glorified smoke dispenser), you delay the light vehicle pressure. In 80% of games I manage to squeeze out an AAHT and turn the game in my favor by the 5min45s mark.
I've seen USF players play double mortar and then wonder how grens/volks/spios just dominate them. Heck, back when I was consistently oscillating between 200 and 300, I used to play one mortar vs OST. I stopped playing it when I noticed that it did jack-sh*t... it's just better to avoid OST MG42 in buildings or behind heavy cover on such lane-y maps and shift attention elsewhere until you get nade tech + captain On Me + AAHT + double pak howi.
Now, if USF had a T0 .50 cal, then it would be another story, but then that would not be USF, that would be a retarded OST wannabe.
In the end, the T0 USF mortar exists purely to give an argument for countering an MG42 early on, without any thought on how building a mortar cripples you in the long run. But again, that's mainly a 2v2+ problem. 1v1, where most balance is made, can bypass the MG42 by just not playing on the side of the map. There are enough points and the map is small/wide enough to avoid even double MG42s without sacrificing fuel/muni nor regular control points.
