Playing SR1 online is like licking the tile floor of the Department of Motor Vehicles.
Big Ass Chains and Team BAC are really spotty for population. Blinged Out Ride, if you get two teams of 6-8 together, is really fun -- but more often than not you get 3 people per side and then two people drop from one team.
But the worst is trying to play through Protect Tha Pimp, which runs a better than 50% chance of having a pair of teamkillers in it who will kill everyone on their team at the outset. Sometimes they're just griefing for lulz, but other times they seem to be clearing the round until they can try the mission alone. Anyway, it's a big, big oversight on Volition's part.
