The "noob introduction days" are awesome. Why? Because it teaches new players right away, before they get used to their bad habits.
You can teach proper trigger discipline, general safety rules (no blind firing, safety on when you're not under "direct threath", etc...). You can also "highly suggest" no hicaps, the use of some form of gear (may it be just a BDU and chest rig with some tan or black boots).
That is a way of keeping airsoft to an higher level. Sure, it needs some sort of commitement from more experienced members who want to run these, but it can work. And to these, accept minors who will be the next players.
Krakens, Broxas can be alright... but sure, someone who gets to a game with some crosman springer or electric shit should be thought what is suitable for play...
