speaking from 3v3+ perspective,
Also 1v1 maps are a lot smaller, so the strafes come in much quicker.
In 1v1 the impact of mass LMGs as soon as you can click redistribute is much higher than in team games.

...
Soviet play containing between 2-4 snipers is less viable 1v1. Snipers are strong against CAS.
The short version is that the abilities from CAS are able to impact a greater portion of the map/your opponent's army in 1v1 and the hard-counters to CAS are stronger in 2v2 than in 1v1.
fair enough. but many 3v3+ maps, especially 4v4, battles are strongly encouraged to occur on the edges, so yeah.
...
1. In 1v1 the ability to suppress most of one person's army is high. Suppressing most of one person's army in a 2v2/3v3/4v4 is less drastic overall.
2. In 1v1 the ISU is not viable on many maps, CAS has no way to ever counter an ISU.
3. In 1v1 PaK walling against one person's tanks on smaller maps (your PaKs can cover a larger percentage of said map) is easier. There are also less people to sweep your tellers/S-Mines.
...
4. also bearing in mind in a 1v1, one can get away without heavy armor, the prospect is a little more iffy in say a 4v4.
1. As the game mode gets bigger, the number of areas for your army(ies) do not increase proportionally. as in more units have to settle with same amount of resting area so to speak. especially when going from 3v3 to 4v4 because there is only one 4v4 only map, which is Vielsam, which is horrendous beyond belief. which means as long as we assume that the blobness of the allies player in 1v1 is same as the allies team in 3v3+, the axis CAS user will reap more from the AI strafe in 3v3+.
2. one of your two/three teammate goes Ele or JT.
if that is not the case, deal with ISU the same way as allies deal with JT. without OP Stuka close air support loitering strafe or matched/superior AT platform, allies teams have been somehow dealing fairly well with JT by making risky plays. I am sure 30 muni recon run helps a lot in making plays.
3. pak/zis walling in 3v3+ should work even finer in 3v3+ since each player has less assigned sectors. i for one love doing it. although once walking stuka or katyusha comes out, it is hell.
4. maybe, but when it comes to armour, all you need is three stug with at least one vetted. it's laughable.
