I'm typing this from my phone so can't be bothered with fancy stuff like quotes etc. For the most part, I do agree with what you say.
Starting off with my major issue with the server right now; Map variety. Frankly, it's next to non-existent. People vote Minecraft, Minecraft, Minecraft and more Minecraft. It's quite frustrating when there are far better maps in the selection. A buffer is much needed, and removal of some older, rarely played maps is much needed also. Removal of one of the community pools is also long overdue.
I've been playing TTT since 2010 and have an enormous collection of absolutely fantastic maps that are hard to come by now that I can offer up as new selections. Stuff like desperados, trappy cottage, lost temple, Cloverfield, concentration camp (admittedly this map is.. contentious to say the least in 2020, but the layout is still top notch.), Space station, the list goes on.
Gun balance is something I'd absolutely be willing to assist in, I have a relatively decent understanding of good balance, having run or co-ran a handful of servers in the past. Unique weapons is the major thing we need right now.. some guns are just near carbon copies or worse variants of other guns.
Staff stuff is not the kind of thing I want to comment on, however. This kind of discussion is best left to the staff team themselves, and I know full well they're capable of coming up with solutions that will work for everyone in the end.
Higashi and I often do not see eye to eye on things, but I can sure as shit admit he cares about the well-being and continuation of growth in the community. That much is entirely undeniable, and I do agree that we need to look retrospectively at some things with the server that need tweaks.
This ended up a lot longer than I expected, but the short answer is, some mix-ups are needed with the server to keep things fresh right now. Primarily being maps and gun tweaks. Thank you for listening to my TED talk.
