armor does not work because zooks + maybe occasional Jackson. Infantry does not work, because Scotts. Stukas are great, but they are questionable value vs competent opponent that has mobile army
Here is a POV from from good 2v2 player, btw this is not his first match vs this strat:

The issue is you can't simply outplay this in any traditional style + it is kind of ridiculous to think that you can get away with spamming mobile indirect. Cali spam can be annoying, but at least you can dive it, they have long reload + they are much more fragile and less mobile. Other indirect spams are either extremely fragile, or can be mitigated simply by repositioning (like lefh spam)
I use scotts in every single game once the jackson or pershing or something is out in the field (not with paths though) and I can tell you that there is not a single situation where you can't do something about it. I ain't watching 3 hours of some random person playing as a proof of anything. I really wouldn't trust anyone playing anything and defining some player as "good" or "bad".
Same as how these 3 are a top 5 arranged team in 3v3 and yet I sh** on 2 of them with a random team, leaving after 15 minutes (played a cancerous spio with flamers SPAM in town part of lienne with OST mortar spam). Don't trust people and their ranks. I'll assume that this dirty guy is a high ranked player and I won't get into 2v2 as I do not play it (seldom watch a tightrope cast when I'm cleaning my place) but I can say that 3v3 spam will never work. I've seen people try and abuse it and fall flat. Also some top 20 players in 3v3 and 2v2.
What I've seen work on most 3v3 maps vs scott + path:
a) Spread out infantry and constantly move them (requires micro)
b) If the enemy has 3+ scotts, then you must have a Panther at least.
c) Send infantry first and do not stop to fire, fire on the move.
( Scott is really toxic on a map like Lienne if you spawn up top. You can hide behind the railcar and spam on the VP, same as how Sturmtiger players have been doing it. Don't know about 2v2 but 3v3 is not really Scott spam friendly concerning maps. )
d) Use stuka before you push with infantry. This will trigger mines and displace the zook blob (and if you're lucky, kill some). Push with infantry and after the first zook volley send in the Panther after the scotts. Scotts might run away but I can guarantee you that you will take down a lot of paths.
One mistake that people do when playing against scott spam is probing the frontlines little by little. Scotts have 0 shock value, A-moving blobs into them is most effective. You force the player to use ground target IN FRONT of the blob to actually hit something, which requires micro. Unless they are some GOD of micro, the zooks will be ineffective.
You want to counter scott + paths?
Gather up your forces, send infantry along the margins of the map to the VP you want to cap (bottom or top), fire one stuka or ask the teammate to help you out with indirects. Keep moving the infantry towards the zooks and then send a tank or two on the other flank to go after the scotts. You require much less micro than the USF player trying to hold it together.
You can't dive one at a time. Like with every SPAM: You make a "Hail Mary" push. Axis is good with those. I mean I play USF exclusively in competitive and OKW in custom games. I won't talk about soviets nor UKF nor OST but I can say without a shadow of a doubt that USF spamming anything and working means that nobody actually tried to be creative to kill it. 2v2 you need to coordinate against spams. A lot of spams are really really annoying. Playing against werfer spams in lategame or JP4 walls combined with obers... it all requires creativity.
I admit that I don't know how to go against a player on Redball that has 2x JP4 and obers + ST or KT. It's a complete lane of a map. Obers dominate fully upgraded rifles from a distance. You need to close in, but if you do that, you go into possible stukas or KT or ST. You can't send tanks because JP4s melt everything. Once won against that only and only because Chris flanked. It was like I was going against a brick wall with a wooden spoon. Can't flank, there are no flanks. Can't smoke, risk a ST wipe. Can't go TD vs TD as JP4s dominate the jackson. Can't force obers to retreat as I have no rocket arty to carpet the frontline.
You just need to be creative.
Is scott + path spam effective? Yes
Is it OP? No
Will it be cracked? Yes
