in my opinion there should be more warnings that items can drop from level 15 due to negative rank or change it to drop from 50 level. in general, you should give more advice to new players and add some dungeons to them in the future.
and get a little bit interested in advertising on a "global" scale, in my humble Poland there are many, many players who certainly have not heard about the server. they just need to be informed that this is not a server for 2-3 months, but you have to play here. I don't know about other countries, but I pay youtubers with real money $$$$$$$$$$ for an episode, some of them have good ranges.
during the duration of the temporary 'academy' server, such an advertisement would be useful.
