I don't really follow, 3000 psi fills for DM does not mean very many shots, or in GEO1 case, couple and hopper. I understand the point of not being able to dominate forward positions, but combine this air restriction with 280FPS limit, it sounds more that these rules are there to reduce need of athletics in the game rather than allow it to flow better. Not saying its a horrible idea to reduce need to be fit to play well, but less restrictions equals more fun. FPS limit just reeks need to reduce shot distance for some goofy reason.
Up to 300 FPS and limit by pods instead of air would be my guess for future evolution if this format gains popularity. Just guessing tho. Will definetly want to try this out.
edit. I must say I really dig the idea behind this, I just find the restrictions odd. I can't just see this working with air limit, time spent on field is critical and amount of shots you can carry equals your forward advantage if you can hold it. When you run out, you need to go and tag your partner in reserve. So, these rules can potentially lead into vicious cycle of finding best marker to shoot as much paint as possible with 3k psi. Egos, timmys, marqs, etc. Whole issue can be changed by judge looking that you have 4 pods in your back rather than checking your tank meter and then it does not favor certain brands of guns and will allow full industry wide support for the format.
