I would like to see something akin to Toontown Rewritten (If links are not allowed, please feel free to remove this whole parenthetical-- https://www.toontownrewritten.com/ ). They add QoL improvements, even fixing the game engine (which I know you guys have done a LOT of). They also add in brand new content every now and again to keep the game feeling like it's alive and well. And to them it is!
Though, if we're the "only" legit server cluster, I could see the need to have an unmodified (maybe just the QoL fixes) server. In case people want the things that came before the SCoRE/HC changes. If this is our chance to go legit, then we should try and be a little more accommodating to those that want to experience the game.
Also, being way more open about balance would be amazing. I've said it a lot to the people I talk to, but taking a page out of Adventure Quest's early development (not sure how they work now), they had balance as an open discussion on the forums. Everyone could find out the numbers and equations that lead to damage numbers, and could make suggestions for additions or balance in an open discussion forum. It kept everyone in the know about how everything worked, if they cared, and allowed for the balance team to focus on game breaking fixes, instead of the small fixes.
I'm also a little biased to AQ, as I worked on their forum as a moderator during those days. (Under a different username.)
But, if nothing else, I like the way HC is going currently. You guys are doing your best, and that's all we can ask for right now. I think in the future, being more open with balance and game changes will make for a happier community, or maybe a little less toxic towards you guys when changes are made. Good luck with whichever way this goes.
