That's not going to happen without a basic set of competitive play/tournament force organization rules, though, because "just take whatever you want" is, has always been, and will always be terrible advice when "whatever you want" refers to 100+ possible options that all do very different things at varying levels of success. Some people will appreciate that sandbox approach for what it is, but others are going to want rules, suggestions, and limits before spending money on stuff.
A basic set of tournament guides, rules, and restrictions allows for people/clubs/cons/shops with no current affiliation or access to the Demo Team to host fair, balanced, and accessible games that can be enjoyed by new players and veterans alike. Does that pose a potential threat to the ages old beer-and-pretzels, everyone has access to everything because salvage approach to the game? Maybe. It definitely might.
So something I mentioned to my local GM years ago was to suggest a "standard" size for games that doesn't change from month to month.
With that in mind, it does change based on the Tech Level (Intro, Standard-IS, Standard-Clan) & the Type of Game (Team v/s Team or Player v/s Player)
Something like this...
Format Team v/s Team Player v/s Player
Unit Count 1 to 4 2 to 6
Tech Level BV2 Max BV2 Max
IntroTech 2500 5000
Standard-IS 3500 7000
Standard-Clan 4500 9000
So as the Tech Grows so to does the BV to keep the sizes of each combat unit similar & the count varies based on if your playing a bunch of single PvP games or 1 big 4v4 Team game.
