Of course level would be a factor like how other content in the game is level locked. And maybe people new to crota might run for the sword but they'd learn, some people actually enjoy teaching people or helping first timers through. And yes the forums exist but they are a throw of the dice only once have I had to boot a super annoying person picked up from the forums, but plenty of the people I play with don't have access to a phone capable of running the app or don't have a CPU to access the site or view the forums as the metaphorical basement of the trolls. It's a suggestion to open the later content up to a wider audience which from doing first timer Vog runs can be rewarding, when you see those users online running it on three times on three 32's a month later with their own team after months of solo play.

Than how would they make a Bungie account you need a phone or a pic to do so

If the forums are such a effective tool why does less than half ever finished a raid

Don't see your point
