In most of the team games I play, the game ends with astonishing speed as after around 5 mins a swarm of kestrels come in and snipe my commander. It has made the game incredibly monotonous to play because the primary tactic is to spam T2 air as fast as possible. I recommend making the Kestrels much more expensive but I'm curious to see others' thoughts on the matter.
This is an exaggeration since 5 minutes to get a t2 factory finished is very good from a very efficient build order. Build t1 AA bots, stingers. They are exceptional at countering air. Also learn to scout your enemy so you know what they are building and what you should be countering with.
I am sure they are getting a bit of a nerf sometime if that is what you are asking. However, you should be able to have preferably stingers, in less an effect spinner and aa turret, and more of an effect flak and fighters. I understand if you don't go air too, but bots and flaks are good.
In team games it's possible to get Advanced out at 5:30 or even sooner. Stingers are good, but easily sniped and only have an extremely small area of coverage. Player's options are two fold: Have stingers protecting the main base. This means you get steamrolled by land units because you put too much into anti-air, or the kestrels snipe the outlying metal extractors and the guy with air control wins via attrition. The other option is to have 1 more Peregrine than your opponent. Advanced air is majorly broken.
I have seen a few games, where peregrines fight and a player takes some stingers underneath. Technically, a player with less peregrines could beat more peregrines that way (and lose a lot of peregrines in the process).
