True, the Seasparrow and Rustler take a fair bit of time to unlock, and after unlocking, you realize Seasparrow is slow as fuck and tickles people on foot it with its gun during which the criminal may just pull out a shotgun or m4 and unload and kill you in 10-20 seconds. Rustler is more for those "camp on rooftop / aerial home" criminals so idk about its effectiveness against people on foot.
Only real way to kill with Seasparrow is to banzai charge them with the Heliblades and hope that it connects and you don't get stuck in a crevice and explode. Even that is not possible against experienced players or groups of +2 criminals.
I'd like to see a small buff to the Seasparrow's MG, not much but a little. And maybe increase its speed a little.
And add some functionality to the Rustler because its not really ideal for your day-to-day Criminal Chases, maybe a bit of buff to the MG to make that 1 second contact with the criminal's car worth it.
Also I've spent 6 hours in a Seasparrow so maybe I am a bit biased
