I made some updates to the game list for what I was missing. Sorry about that; I copy/pasted most of the list from an event I'm hosting.
Counting every droplet clearly doesn't work. A mist droplet to the waist will never get noticed, nor is there demonstrable marking/proof. Overall, we are still developing our hit system as we play, but I think we can all agree now that little bits of splatter would never count. Anyway, oncoming storm brings up a good point on why we never use riot blasts; standard streams are just as effective close up.
The light/medium/heavy definitions are still subjective, but we have a good idea of where they are at this point, and more importantly, we know what's permissible in each class. Vanquishers can operate in both light and medium primary territory, as it has features that make it competitive with mediums without making it overpowered for lights.
Overall, we still can't settle into more concrete definitions, but the "light primaries" definition is much more convenient and inclusive than "BBT only" or "air pressure only" categories, and that's ultimately what I'd much rather have instead of dealing with and packing for pointless categorizations.
