Teamgames are a different story and stukas are better there because everything is more congested, but so is other rocket arty.
But in teamgames allies can pull some BS too. Multiple scotts is really strong and pretty hard to counter (a lot harder to dive than stukas) but does come a lot later I guess.
And even with "resource inflation" that particular guy's first tank will be 100 fuel slower. Imagine waiting until you had cost+100 fuel to build your first tank and take that into account too.
It is not difficult to get some AT guns as axis. And the only early threat of AT gun which is indirect fire of team weapons simply doesn't exist due to the dominance of stuka. And every axis mainline infantry has Faust. So camping at fuel point is easy. The difference for one having fuel points while another not is huge, that's is a +7 and -7 fuel difference which sums up as 14 fuel difference for one fuel point only and two fuel points is 28 fuel difference. You just have to utilize your early strum advantage and camping in fuel point for like 4 minutes, you get a free stuka while having same amount of fuel as your opponent.
