No you’ve misread what the suggestion was… The matchmaking wouldn’t change, you’d fight players of any level just as it is now, but your points total would be tabled only against players of similar levels…
@lyya yes noted that @sirrian did post that, and the point about players slowing levelling to manipulate their position…
…but I don’t get it - I don’t think slow-levelling is a worry because anyone who slows down wouldn’t be competing on the leaderboard! I posted my thoughts here Avoid the MPQ path - #65 by Jainus as I’m sure @sirrian has this thought through better than I do, but @sirrian hasn’t had the time to respond yet…
