Umm, I guess in a perfect world it'd be kept at D2 current Light Levels to keep it relevant. This is all assuming D2 works similarly to D1.

Just a question that must be asked you know? How long before we surpass the light level and can complete it with a few from 3-5. If they aim for balance, there will be a set amount of dps and it will all factor around that, once we surpass its light level we can reduce the number of players needed. If it were a 6+ raid, what would the max number be? Also have to take in the consideration of connections, I've had a NAT type problem with someone before, I could not hear their mic and it kept kicking me to orbit shortly after joining.

I think the max number could be 12 maybe? As for people running it with lesser numbers; I feel mechanics could be put in place to halt that from happening. Otherwise it'd become a Crota Strike and that happening again would be kinda bad.

It's not a bad idea and can be fun, but the community would need to make shorter versions of raid guides. I once thought I would try Kingsfall and since no one wanted to take inexperienced at the time, I looked up Kingsfall raid guide and saw one with over 1-2 hours footage and had a good laugh and thought, "-blam!- that."
