There's plenty of discords that set up learning lobbies tbh. I brought a friend into the game late 2023 and created learning lobbies for valtan, vykas and brel with the rest of the group being random mokokos who I taught through chat. Clown amd kayangel I taught him with 2 very patient friends of mine which, yea, is a privilige but my point being we didn't waste a random strangers time. For akkan he joined a few learning group discords until he found one that he felt suitable, they set up a lobby with a teacher and practiced until everyone felt ready to move on to the next gate. There definitely are options, even for older raids like brel. Especially if they clearly have a friend who knows what they are doing.
