Yes changing the grenade snare vet 1 ability is going to cause a very big early game problem for USF. Bad move.
Also how is the Scott OP? If you can micro it, its OP, like DevM, but that doesn't make it OP, it gets killed pretty easily and this nerf will overshadow it by Sherman.
Pack Howitzer is important for the USF since USF doesn't have strong artillery.
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.
