Regarding the 1000+ total level worlds. For all the updates Jagex has ever introduced that I did not like, I have to say this one disgusts me the most. The exclusionary elitist ideas behind this update literally makes me sick. So many times players have home worlds and although not everyone is added to friends, their are indeed literally hundreds of acquaintances you make, and you just threw that away. You eliminated the human side of your equation when you did this Jagex. If some people don't want to be bothered dealing with "noobs" they have many option on chat features and choosing where to hang out. I am combat 137 with 2100 total plus btw, and I think this update is on the verge of evil. With no warning whatsoever people are now cut off from those they were becoming friends with. I can not financially support such an inhuman and unfeeling company. I will be canceling the accounts of myself and my sons. Id rather throw that money in the trash than give it to a group that does this type of action. I call on all paying members to strongly consider boycotting this elitist group until they recognize the human side of the "noobs" they have displaced.
