I feel T1 air destories anything t2 way too fast... like I build up a army of kestrels and then like 3 hummingbirds and just destory them all in like 15 seconds.
maybe leave them 3-4 shot, make them a bit slower, and also add some more damn variety to fighters like longrange high damage low rate of fire and health, and high health low range multimissile with low rate? one would be better attack, one better defend, and one used to peck from safety.
I definately feel they are too strong right now although they aren't far off right in respect of other units. A 20-30% reduction in HP would probably be enough or maybe a severe reduction in visibility like the dox got hit with.
