For the first time this week in recent memory, many of the matches were not decided on reset night. People are actually gasp interested in playing hard the entire week because 5 to 6 of the 8 matches in NA actually are relatively fair match-ups based on PPT. Please take this into consideration going into the leagues. If you want to bring back server stability, put more limits into this glicko system you have.
1. Make it easier for transfer servers to climb rankings so they don’t torture lower tier servers for weeks and make everybody unhappy. Seriously, you read the forums (you claim to), make glicko adjustments based on even mundane things like server, or more specifically wvw population for the week.
2. Opposite of number 1, make it easier for servers that are dead or dying in WvW easier to fall to the bottom so they stop the bleeding of people leaving every week.
3. Give people variety, but be reasonable. Nobody wants the variety that is associated with getting roflstomped and spawn camped 24/7. There is a fine line between variety and stupidity and this system often crosses it. You can provide both variety and stability, it isn’t just one or the other, just be reasonable in RNG limitations. Make it harder for servers to be matched up out of their tier but still possible.
4. Leagues are a mistake. Tier 1 is without a doubt and pun intended, a league of its own. Servers buy guilds to enter into PPT&ego driven lag&queue fests that will only get worse when PvE players try to cram into already bloated tier 1 servers for meta achievements. There is no room for tier 1 players to play WvW on their own servers (because of the guilds on those servers own stupidity), and also no way for anyone outside of Stack Quarry, Sanctum of Stackers, or Stackgate to compete with the likes of their game-breaking coverage.
