This has been on my mind lately too. It's very odd to see an FPS without rockets of some kind. Battlefield, CoD, TF2, they all have them, so why not Brink? My guess is that they just saw no use for them. Grenades were made to be supporting items, not killing, just knocking you down. Rockets would have been the same way, I feel. They would knock you down, but not kill you. Since the game was designed with explosives taking a backseat, the developers probably saw no point in adding rockets. While I do enjoy running around with them once in a while, I honestly don't think they would have had much of a use in Brink anyway. I guess we get to enjoy the Lobster for now. =)
