Exemple of what you'll see on your group:
"Ho s*** its so laggy! do something!"
"Ho yes, I will... Do nothing as I have no power on it"
"There's a bug at XXXX! Do something!"
"I'm not the owner, so I can do nothing"
"Can you add this or that?"
"No"
"If there any way that real owner speak about his server?"
"Don't know, I am not speaking to him as he speaking to no one"
So yes, you're group will be useful for community who want cry and scream...
But you'll never make anything change, even if you're thousand of people crying and screaming.
Owner don't care about what happens on his server. You will never change that.
