I just noticed/thought of something -- party forming and items a party can get from a run.
If I am a more advanced player, I can get into groups doing HardMode and higher stage(DB) dungeons.
If I am less advanced, new, returning, or whatever, I am excluded by many advanced players running groups only for other advanced players. This will tend to compensate advanced players with higher mode equipment, pushing them higher and higher while less advanced players remain stuck at lower-tier equipment.
This is discouraging to those who aren't advanced, as there is no way to get higher tier equipment unless you are advanced enough to fit in with advanced groups.
I'm not sure of an ideal way to compensate for this, other than have rewards be the same for all dungeon levels, which would be fairly unpopular, or form groups either fully or partly at random upon entering a dungeon. I say partly because friends like to run with friends, but if half the party was composed of a random char wanting that dungeon, then less-advanced players could get a chance at better equipment. Now I say 'random', but it might be within some bracketed level, say plus or minus some number of HM-levels and/or a weight AP.
As it stands its very hard for those starting out at some deficit to ever catch up. Related to this is the advantage advanced players have in being able to sell "carries" through a dungeon to allow less-advanced chars to buy equipment and such -- which I'm torn on, because, it can be a way to support a gaming "habit", but it also matches the saying of "the rich get richer, and poor get poorer", which promotes some people working hard, but also can be oppressive when the gap becomes too large.
Ideas? Ways to lower the (https://en.wikipedia.org/wiki/Gini_coefficient) of the game (as applied to game riches)?
