OK, thank you but I do know how achievements work in pvp. I am sure you meant well as some don't understand how they work still and we have had freelancer since HWs
Now lets cover a few things these same people that scream murder that they don't want to play with others are freelancing. Next you just admitted they are refusing to que other GCs while getting their mount. Finally and the most flawed part of your response. Somehow those people freelanced and won on adders and flames. Yet at the same time while they were winning on the adders and flames only 5(maybe 4) of those adders and flames got wins as well. You can not seriously be using the they might have won as freelancer. The math to make that leap is astounding. Someone who is way better at math then me could probably come up with some sort of formula/number. My just number out of the air. Is if one GC has over 80 of 100 spots they are not freelancing. That would still mean that one GC has at least 8 times more winners.
What also came up today with some one was "How would these same people feel if a group found a loophole to que a full party into feast?" I was kind of shocked I hadn't thought of that. But I am sure also some people are on discord and move into channels with each other when they get together in a match. So maybe these people don't care what they do to get wins, was what I came up with.
