The first problem is that the small dungeons and raids are not lucrative from the rewards for high players.
The second problem is even if you want to help 50 new players you can only help selected players 1 time because you don’t have the raid access for it. So 44 players are denied the help.
The solution could be something like a mentoring program that takes care of small players and helps them in the early dungeons and raids. And you as a mentor get materials silver and gold as an example.
For the lack of experience portion, Smilegate can create a mentor incentive in the game where those with a lot of experience can run learning parties and get extra rewards for that because we all know a generous person is very rare in this game (unlike Final Fantasy). At least with the incentive, the people who only look out for themselves will at least get something out of assisting others by teaching them the mech in game after the new players watch a guide video or read a cheat sheet.
that wont work
either reward will be to low no one will do it
either it will be abused
either the reward are good enough so ppl feel forced to do it and you get ultra toxic grp
New players are free to create learning groups, as we did when each content was released. Take experience and then claim experienced groups. There are stages that new players want to skip, but it just doesn’t work that way.
Not alot of people gatekeep you for roster level my roster level is quite low for 1545 ilv player and i never got refused in a party where there was spot lol
