The mutator is a server side addition, To my knowledge it's still going under tests and they're working on it daily. I for one am sick to death of idiots constantly over-mining in dumb places to screw there team over. Getting a eva message to your to team informing you of who has over-mined is a good indicator to inform the whole team who's the person responsible.
It has nothing to do with big brother, it's about making the server better so everyone can enjoy it.
Also the team gets the message to my knowledge as that part of the mutator has been fixed.
Refering to your 3. When a lot of people over mine the announcements become like spam
So this mutator seems to annoy you, but the constant stupid "building need repair", "move out" "fall back" spam is all right? 9/10 those spams are not useful, and just people being tards spamming for the sake of it.
I like the mutator, it's nice to see people within the RenX community actually taking an interest and helping out to support there community, the only people i truly see complaining are the ones who don't contribute at all, come on a server and bitch that the server sucks, it lags, crates are shit, crashes etc.. Newsflash for you all it's BETA3 .. Instead of bashing the server, why not take it up with the devs?
