If you think the patch was pretty bad, fair enough, you're entitled to your own opinion.
I do agree that the AAEPD would rather need additional changes against that 100m anti-player effectivity. Hard damage change was fine and very much needed though.
As Kempington said, the ISSR-B is too much of a good gun, even against vehicles, and you could fire it hanging out a window. Not okay.
ISSR-A, yeah, already a bad and underused gun. This was adjusted to match the ISSR-Bs values, not to make the gun any worse.
SWARM at 50.7 hard damage wasn't fine against the new vehicle health pools, trust me, we tested that thoroughly. It performed too well against players and vehicles at the same time.
Random recoil + patterns were always a thing since recoil was introduced to APB. Check the SHAW and ALIG for example.
The vegas changes - the 4x4 isn't "basically the same car with different steering."
It's very much a different car, handles extremely different and is very fast at all times.
The regular vegas however is a brick that just asks to get killed unless you're already moving, and if you're moving, you're moving in a straight line.
There was zero reason to use the regular vegas over the 4x4, and it very much needs the higher health pool to make up for its slowness.
