You want to pay them money for the opportunity to add more admins? Couldn't that feature be added for free?
In the past, hosted servers required official hosts. And license deals. And rcon. And leaks. And pirate servers.
I'm not sure EA wants all that. I think they want total control of the servers and who get access to the code and commands. They theoretically could add what you want, but it would need to be another field in portal that you could enter as an array of authorized usernames or something.
Personally, with how poorly they are handling the bot farms and xp issue and how badly the servers are performing, I would never pay money for something that is not guaranteed to solve the current issues on that front.
Like, really, how hard is it to revoke approval for bot farms they previously approved? Bot farms are STILL one person start, full XP and full unlocks, and destroy global server performance by making one whole server of 64 slots wasted on one human player. How hard is it to make every other server 1 person start with full XP? So the experiences EA pretends to encourage can actually be competitive, populated, and discovered by others? No one who is currently being punished for their legitimate empty server has anything close to damaging as the bot farms EA pretends to not condone. EA is a AI intern with a bunch of bosses with fingers in their ears.
They have broken promises and broken trust. They don't listen to their core. They have shown that they are incapable of even attempting to achieve their stated goals. You think all they need is more money? I seriously question if anyone is even listening or thinking. And I wonder if the talent has already moved onto another project. It seems the people in the source code now are not the ones who originally understood it.
