It has always amazed me that
People enjoy playing at 10FPS so much for whatever reason that they will purposely look for only this type of content.
ArenaNet has gotten complaints about lag in WVW for years, but has done nothing. Instead they push balance towards favoring comp builds, full squads, and map blobs which makes the lag problem worse. The roamer meta used to be power builds, now it is Cele or Minstrel so you can survive long enough to call mapchat for 3 people.
Mounts have not been nerfed. 95% of builds cannot escape a larger group that is repeatedly lancing and dismounting on them one at a time, then going out of combat and doing it again because mount is faster than players. This phenomenon alone is so beyond stupid that it is still in the game, and it is actually braindead that the devs don't see a problem with this.
These problems have basically ruined WVW. Players that somehow enjoy playing Microsoft PowerPoint and ArenaNet addressing the lag and blob problem with a general attitude of 'just go out there and zerg bro, WVWers want giant fights only, because when we actually play this mode all we do is zerg on Maguuma'. Mounts making it so unless you are on the fastest/stealthiest classes, you are literally dead the second you encounter a larger group.
Really, the main zerg audience of the game and the devs deserve each other since their negative IQs probably match.
