Using the ranking system provided by ANet, there is a 200 point gap between 4th and 5th position, which is the largest WvW skill disparity, meaning that after the top 3 grouping is established, whoever is tossed into the meat grinder with the remaining team, has an extremely high probability to lose.
I currently play on Blackgate with about 30 other friends and guildmates, and we’re already looking to xfer off since we stand no chance against the night crews from any of the top 4 servers. We have faced all of the servers in the top 4 on a regular bases the past 2 weeks, it’s extremely evident there is no hope.
The situation for the 3 servers listed in the title is extremely simple: Try and win and you will lose forever. The only way to have a chance to win is to hope people will xfer to us that are good at WvW (which won’t happen, they will go to one of the top 4) or just roll over until we fall to a lower bracket so someone else gets screwed.
Blackgate and Northern Shiv had the same problem. Both were very dominant early on; only to have 4-8 big guilds transfer off and they slowly declined in ranking/wins in WvWvW.
