I have explained why its a poor idea.
I'm not twisting. You refuse to answer questions and keep repeating yourself despite multiple people coming to you with issues and questions. Instead you repeat yourself and add exclamation marks and bold lettering. That, to me, is whining and stomping. No, you don't need to use boldings etc.
1. Your idea will further fragment the community. Its already split between PVP and PVE type players. Not only that, it will further fragment by levels. What will be the parameters? 10 levels up and down? Or will it just be 1-10 bracket, 11-20 bracket etc? (if using 10s)
2. How will you address the further complaints for "fairness?" We have already seen someone say any level difference is unfair I believe, and people saying ONLY within 5 levels is fair... do you not see how fragmented the community will be if we have brackets of 5 levels?
3. How does further sharding address issues with groupings? If I am outside the 5-10 level cap of a friend, what happens? Are we just phased until we are closer?
4. Why isn't opting out of WM and just joining BGs and Arenas not sufficient? By suggesting this I am not saying ganks and one-shots don't occur, I'm saying they aren't as big of a deal as you make it out to be. And while that isn't EXACTLY what you are demanding, it 100% (as told by several others) almost exactly what you are suggesting. "Fair" PVP...
