Everything before illusion is very outdated and just holding back players from getting into the new relevant content (17.1 and upwards). I think the majority of players who join this server already done all of 16.1 and previous eps 100 times already with a few rare exceptions. It's not fun to do for things that dont even matter anymore nowadays
Kinda everything up until illusion is irrelevant to the max. Today i saw someone literally doing ep 15 to kill a monster from the eden board quest lol.. and it didnt seem like he had lots of fun doing so.
My suggestion would be unlocking everything before 17.1 upon char creation and make the quests optional for those who still wanna do the quests.
