I am not sure you can use this for anything, but if constructive feedback can be useful for you all, to bring back the glory that was once CoA, I will be happy to share my thoughts. Three things led to me departing the server.
The first, was that part of the Player base, supported by the most active DMs on the team, effectively changed CoA from a roleplaying server, to an action server. The mechanical challenge became more important than telling a good story. Values of "playing your stats", "telling a good story" and "rewarding interesting concepts & builds that portray something unique", as well as focus on a major narrative through the setting, were replaced by maximizing the mechanical challenge, and surviving insane encounters. If you survived, you got epic loot, and epic dm attention. If you died, you got told to "get better".
The second was the death of CoA Europe. I work long hours, so I could only give the game roughly 10 hours a week. And for a mover & shaker, I experienced it as almost impossible to have any impact on the game. This was caused by the Plot DMs being purely American based, so plots and progress occured outside the 17-22ish EU timezone. This made players in the EU timezones leave, and killed off the time zone entirely.
This leads me to the third "thing." Improper Community Management. With the death of storytelling and focus on mechanical challenges, with the balance between EU and US timezones, buddies of the active DMs were rewarded, and the RP focused individuals slowly drifted away. For years, we had 2 or so active IG DMs if lucky. That is not nearly enough, and it led to frustrations and stress being taken out on the player base. Instead of collaborating, the mindset of the playerbase drifted to competing for sparse DM attention, and the gap between those who had it, and those who did not, became bigger. To put it bluntly, you began nursing the weeds rather than the flowers, because the flowers needed more care, and the weed was resilient, did not have too many demands, because they only played when they needed a break from EFU.
Instead of maintaining the differences between EFU and CoA, you allowed the worst from EFU to be brought into the CoA community, and laughed at all who argued against it. And now the flowers in the garden are gone, the movers & shakers, and the storytellers have vanished, because you wanted to play "who can spawn most suicide goblins or run epic death traps for your EFU buddies.
If you want to change it, change the mindset of some of the current DM team, or remove some, who have burned out, and are effectively no longer contributing positively. Reach out to the Netheril community, and find common ground, and a way to combine forces once more.
I wish you all the best.
