Its funny how you bring up what used to happen before December 2017 as if it has any relevance with the current situation.
Compare the AA capabilities of the Quad with any other AA weapon you will find them far superior.
What I have posted is that AA capabilities need an overhaul (some units AA is to high and other too low) and critical kill system of planes should be replaced.
That depends on how you define "superior".
As a sidetech, It SHOULD be superior, you're not going to put STGs or LMGs on Obers or Valks only to find NOT give you an advantage. In addition; as someone has already stated, it comes as a vulnerable light vehicle and requires you to upgrade it.
The pre-patch is still relevant, whether you agree or not. OKW Actually did take any Air support call-ins off the table, especially the lend-lease drop-seen as it has to come over the enemy base, and now that its gone, people suddenly start all the AA hate because it does what its meant to do.
Although, I wholeheartedly agree the OSTWIND needs a buff, Maybe a small one, but a buff none the less.
And I think the changes to the planes (essentially making them paper planes) was probably a little too much, I mean seriously, they have the durability of a paper plane in water.
