Auto Sentry Questions

ok 1st questions has anybody used the auto sentry and if so what is its pros or cons. second does anybody have a good analysis on this AA? if so post your thoughts here. and please stay on topic.

Dont know much about it but from some gameplay and what ive heard it seems really useless but like i said idk waiting for the game to see for myself

It seems to be a defensive AA. Like defending a base or key chokepoints.

I guess it can be useful at some times to get an advantage on taking someone out,but its very weak.
