I hesitate to call them this because it's ridiculous but- "Controversial Issues" like that where the playerbase is vaguely split. Explain both sides of the story, find out what the developers think, even try to interview them and then fail because they don't talk to us about said "Controversial Issues". Talk about Nick's quote in the testing forum, and about what players thought.
What does that gunners don't like the wheel-o-changing weapons say about the game's design?
Things like that. Ya. You probably already do discuss them, but if you don't then you should.
Gunners don't like the wheel? Why wouldn't gunners like the wheel? Surely you don't mean the exploiting part of playerbase that abuses as much they can weapon-switch-animation-cancelling?
