We’ve been keeping a very close watch on this week’s matchups and, despite our concerns regarding the recent population shifts, it seems that many of the games are quite competitive. At the same time we’ve been evaluating some possible changes to the math we use to calculate ratings. After examining a number of new methodologies for weighting the outcomes of matches we have found that our existing formulas already do pretty much what we want them to do. Certainly none of the candidates that we tried yielded better results.
In light of the strong community response to the idea of a WvW ratings reset, the results of our ratings formula investigations, and our data on the current matchups we have decided not to reset the WvW ratings at this time. All existing WvW ratings will be preserved and the rating calculation methodology will remain unchanged. Any existing mismatches should be corrected by the system in relatively short order. Now that there is less volatility in the player base for each world we expect the quality of matches to improve more quickly. This is both because the rating system is operating in a less unpredictable environment and because more stable teams tend to produce better results.
Thank you all for your feedback on this matter, and for your patience while we explored the various options. The community response was a key element in our decision making process.
Edit: Matchups site already been edited to reflect predictions for next week with correct ratings.
I can't help but think ANet weren't sure how to change the math behind the ratings that they reverted it, coupled with the the backlash from the community. I'm just really disheartened that this news came 27 hours before reset.
