People don't like Huttball because they are bad.
If you're a good pvper, who knows how to communicate, then it's by far the most fun map to play, requiring the most strategy and coordination. Every class DOES have it's role there.

That said, new maps > new hball maps. I don't think they're/we're out of ideas this early. Though they've been saying the new wz map will require a lot more coordination, so most of you will probably hate that map too. /shrug
