there's actually a bit more than "a few things" but i'll try to keep it concise. server stability, arbitrary rules, stubborn staff when it comes to decision-making (it shouldn't take months for "active" staff to come to an agreement on something), and unfair treatment of players would be the bulk of it all.
honestly, i could go through every issue the server is facing, come up with solutions to all of them, hand the directions to the current staff, and nothing would happen. they'd rather suggest that there are no issues, and player counts have dwindled because "it's not summer yet" or "people are just busy" rather than acknowledge that problems currently exist.
this post is long enough, but if you're up for it, read this thread:
