i think you missed my point there, i am just but a mere player, i neither handle suggestions nor are saying a server is more superior than the others,
i am just saying that you should play the server as it is supposed to be, suggestion are fine but make it so that it is still preserving its strong point that make it unique that people are enjoy playing, which in semi-vanilla is "mostly vanilla",
sure you can request any non vanilla feature to be added to semi-vanilla, the prime example is looting 5 which even classic doesn't have, but they weaken and eventually erase semi-vanilla's strong point, you might be fine as it is your idea, but others, especially new players might not, eg by saying "oh this server isn't what i expected it to be, i better find another server",
classic might look like too op for you but it is actually pretty straightforward, classic is vanilla-ish economy server with ae as its #1 strong point,
while towny is similar to classic except it comes with completely custom gameplay, simply put, rpg-ish,
on the other hand semi-vanilla is mostly vanilla, do note that since it is bearing "vanilla" in its name, new players expect it to be vanilla since that is the reason they choose the name,
btw, i don't play in semi-vanilla, so what happened and what will happen to it corcern me not, the reason i don't play semi-vanilla is that it offers too few goals to reach, eg, killing ender dragon, or getting all materials,
on the other hand, as much as i interested in the rich-featured towny, its seasonal nature with completely different features and/or world for each season prevents me from playing it, lets say that i grinded hard in towny for weeks already, and the next month, towny will be completely different, as if what already happened was just a dream,
therefore i only play in classic, since there are so many goals to reach, eg getting heroics aes, to be the richest is the server, and so on, and classic is extremly stable, what i built there 3 years ago is still exist even now, and the mechanics are hardly changed..
