Since the ladder and Patreon servers are pretty much dead, I'd like to make a few suggestions for them.

1. Ladder/Reset servers need incentives to be played on. This doesn't need to mean "exclusive gameplay content" like league mechanics in PoE but something like a reward system for completing x% amount of quests or reaching level y would already make people more interested in playing it.
   Exclusive armor that can be slotted into the vanity/cosmetic armor slot would fit that bill very nicely. (maybe a body armor with a "1" on the back for season 1 etc.) Does need a system to freely claim those items on any server/character tho. Since they are cosmetic, they'd always be level 1.

2. Many dislike the thought of potentially losing progress on a reset server. The way that D2/3/PoE get around that is by changing those characters into non-ladder characters. One way to achieve that would be to merge the characters that exist on both servers, or simply only keep the higher level / quest% one. Additionally, the world save should be made available for download if anyone wishes to continue in single player.
   Lastly, and this is probably not easily doable, would be to add the "overworld" world as an additional dimension on the main server. This would potentially conflict with minecolonies and other mods, so its most likely not doable, but maybe worth looking into.

3. Patreon server won't ever work unless there are enough people that have patreon status who are also interested in a private community. Since the public servers wont even fill up enough to warrant a private community, this server is best to be cut imo.
   If possible the server cost could be redistributed onto the existing servers that are used more frequently.

Hey thanks for the feedback!

1. I have been contemplating a way to provide rewards from the the season servers into the legacy servers without making them affect stats, I forgot about the cosmetic armor and that's a good idea. Ideally before, I would have had the "season" servers non-Patreon, but the Patreon players voted for it and that's why it remained this way. And then I simply dont have enough resources for a 4th server at this time which would be a reset server too.
2. The problem with sharing the world saves is that they easily reach 10's of gbs and I can't really distribute them. The idea of losing progress ties into the above with getting some sort of legacy reward. I thought it might be cool if on the season servers once a certain challenge wqas completed, the legacy servers would receive some sort of boost. Not really plausible since the season server is patreon.
3. Server cost for Wrae and Trist are already at the max cost-benefit. There's no reason to give them more resources unless I make a new one. Patreon server has been pretty dead lately, but it was very active before, I'm assuming it's dead because it's the end of the season, and am continuing to monitor for this season. If it remains dead even after the start of season, I'll think abotu it some more. One thing is this: I can't simply take the resources from Patreon and put them into the other servers or make a new one necessarily. The server is literally funded by Patreons and the benefit of one of the tiers is that they receive access to the server. So unless I restructure how my Patreon benefits work (which I may need to do later), I can't just remove the server or that's not fair to the current Patrons.

Hopefully that helps. TL;DR It's already something I was thinking about and I like some of your suggestions. Suggestion 3 isn't quite feasible without some structural changes.
