Someone mentioned smoke bombs. That could be a lot of fun, adding to the WTF-style chaos where everyone in the AoE loses visibility. Although with the current targeting system it wouldn’t much affect fights happening “in orbit” away from scenery. Hmm. Perhaps if the AoE allowed targeting and killing (well ok, teamkilling is rarely fun, maybe stunning instead?) team mates in the team games?
Perhaps a variation in popping smoke- popping decoys. Drop a handful (no more than 4-5) of shiny objects that can be targeted and destroyed like players. It would aid in a quick getaway as people end up targeting the decoys. To make it less frustrating for the attackers maybe destroying a decoy is the equivalent of collecting a star?
Perhaps once enough good and viable ideas were gathered, the three mega-perks could be expanded into three small lists of mega-perks, where you can only choose one from each list? It would add variation to the mid-late game while not unbalancing things completely.
The main combat mechanic doesn’t and shouldn’t be altered drastically, as far as I’m concerned. Ok, the targeting could certainly be tightened up, but the basic lock -> dash -> kaboom is, at its core, solid, entertaining, sort of “dogfighty”, and chaotic enough to mean that you can get very good at it, but it’s never a sure thing.
