We can't disable manned guns and I really do not think we can adjust the alt on puff ack. I would love to be proven wrong on both trust me.
To add to all of that.........
I don't want this taken as a whine. Trust me, if I plan on whining, it will be well thought out, researched, and posted in such a long fashion that it will put you to sleep.
For a "free for all" type arena (which it is right now?) to just have some fun until the next setup, it really blows to be sniped by 5" guns in the middle of a good fight. Especially, when the habit is (on both sides here, not pointing fingers) to stay near the ack, which is only a natural reaction. Also to dodge puffy ack when fighting above 3K is also a bit annoying. I know the inherent risks involved with chasing someone into he ack, but to be singled out by some yahoo in a 5" gun (some of whom I have never even seen take to the air) is silly.
If this were a situation where there were objectives, or a plan, and CV's were part of the plan, then I wouldn't even be mentioning it.
Conversely, I am as equally pissed if a friendly does the same thing to someone that I am fighting.
I know that there is a DA for this, blah blah blah, but the caliber of the fights in the AvA has traditionally always been a bit higher.
