Boardwalk is one of the more ridiculous maps that allows the jetpack to be negatively abusive. Reflection and some of the forged variants from the community are also hit hard by it. Then there's maps like Zealot, Powerhouse, and Countdown where I haven't necessarily found its presence as repulsive. Still, I think where maps like the Jetpack isn't absolutely terrible, it's something else that is, like Camo. A team of Jetpacks on Pinnacle or Countdown may not be as harmful as a team of Camo players. Those two AA's, along with Spartans using Evade, are the three absolute worst things of the game. They're not available at all times or in every game mode or playlist, but in a lot of moments they're quite annoying to face. I'm sure we'll find similar things in H4, unfortunately. Once Regen Field gets introduced and gets to be used on small, enclosed maps, I'll probably be want to break my disc.
