If im not misteken i think the guild system watched teams up by rating instead of rank -.-;, ive had that happen so many times. Since you have a screenshot, id sumbit it to the game glitches support section at the guild wars main site. Maybe theyll fix the system...and if its not the system it mightve been taht youd been set up with the ONLY available team at the moment XD
Last night Te played a rank 8,000 something, it was sad. The other team also had half their team as henchmen. It was the most one-sided gvg I have ever seen.
I'm thinking the problem isn't the system, it's time. I mean, really, only so many guilds are trying to GvG at one time, and Guild Battles normally last a fairly long time. They've often very very few people to choose from, I 'spect. Less a problem with the system, and more a problem with YOU.
When I was trying to find a guild that suited me one of the ones I checked out was new and unranked, and the very first gvg it was us unranked vs a rank 26 team.
