I don't even know where to start.
First of all, USF will get the snare after unlocking LT or CPT which costs a total of 35 fuel, and considering you have 20 fuel as a starting resource you can get LT or CPT as your 3rd unit if you want to. WHICH axis vehicle is the problem in this time frame? Kübelwagen? 222 and Flame HT comes after you get a officer and the 221 arrives at the same time if not later. Please elaborate the "very big early game problem" USF will have with the snare change. This change is a straight BUFF btw. Not sure why you would complain about a buff to the faction you main.
Scott is OP for obvious reasons. It has 400 HP + smoke + range + can shoot over buildings which makes it next to uncounterable unless you make extremely risky dives or have Elefant ready to counter it on open maps where it cant hide behind shot blockers. Just a braindead unit as it currently is.
Pak Howitzer is batshit OP compared to Leig or any other mortar and nerfing it is a no-brainer which basically anyone that plays more than one faction agrees about.
Agreed with most of the post. Pak howi needs a nerf in the accuracy department, not distance damage. Scott should be 2 shot, not have autofire reduced since the autofire is even in the current patch mediocre at best, even vs blobs. It's really RNG dependent. You either induce rage in the enemy or you just sit there and watch how the shells do 0 dmg. Also, Scott can't fire over buildings in autofire, only in ground target and barrage. If you try press ctrl-A anywhere, the scott will try to completely close in on the target (literally stand next to it). Some bug or something. So it's micro intensive, like the whole faction.
It's also a bit misleading to compare pak howi to leig. They are both "heavier mortars" but alongside leig is stuka. Leig is much more consistent at dishing out damage (while having lower damage profile).
Reduce pak howi autofire accuracy, buff barrage and call it a day. It won't reliably hit without any input and barrages will be reliable.
Also, Pershing needs some sort of survivability or ROF buff or something. Right now it's price does not fit the performance.
