I've been pretty happy with the special ammo situation after the most recent changes while sidearms and icebreaker are still prevalent, seeing a lot more variety, and am not caught quite so often without special ammo.
Mostly killed by shotguns when I'm blindsided with them; ill conceived rushes (by me or others) still seem to be shutdown with primary fire just like before. Supers are a problem, so I just try to move away from teammates to create space and punish poor choices by the person using the roaming super.
In my skill bracket after the host-selection has settled down a bit I'm only noticing 0-2 bad connections/game, usually as part of larger fire teams. Most egregious red bar yesterday was solo queuing, though. Dutifully reporting everyone I see that's teleporting. Still think there's some flavour of bad connectivity that the bar size/colour doesn't represent green bars that die to my gun fire/melee after they've killed me with a fusion grenade (etc I wasn't red barring).
