On the point of Server expansion. It was just recently expanded, with a player cap of 1800 players on each server. For an amazing small staffed MMO that's money out of their immediate pockets. They've already talked on plans for bigger player caps/more servers.
As for Server Stability, this game is getting the attention of a few high end YouTuber's. This is causing an influx of Players, which in turn attracts the likes of DDOS's. The game goes off once a day for maintenance, which you get a message before hand. Other than that the Server's are fine I never disconnect unless the stated above happens.
So let me wrap my head around this. You want shorter Queue's, but want the AFK Timer to be removed. You can't have one without the other. The AFK Timer is fair, 1 minute to go AFK and around 5-7 minutes to be kicked. If you don't wish to get kicked you can turn on Mouse Key's for your computer and use a weight to move. You can download and Auto Typer and create your own Chat to Type in to avoid the AFK Timer. You can download a Mouse Shadow which will copy the one move you tell it to do. All of these are legal ways to avoid the AFK Timer, all of them are made to avoid the timer but will not give you an advantage in any way, shape, or form.
All of which you have suggested has been read and answered many times. If you really wish for the game to be perfect why not contact the Owner of the game and see about buying a part of the Company? If you can't do that, how about you donate the money to get another server? Or you could buy a membership every month for $5 which they can use to upgrade.
you can have lil to 0 ques and have the afk timer removed. its called expanding/ adding servers and dont have to restart your account ona new server which is also lame.
I plan to get a membership every month along with my gf and if the shop gets better ill buy stuff off that. its not much but its something.
Everyone that works on this game has a job outside of it. Some of them have families and other things to provide for. Unless you have the money to pay for another server up front then you'll have to live with it. I wouldn't want them to take money out of the mouth of their families just so you can have an immediate login. This MMO was made for the fun and love of the game by hobbyist with a passion for what they do. Everything you suggested will happen in due time, be patient.
