I'm pretty sure that lots of players are trying, as I am, to complete the whole map exploration, and even if I didn't believe when I read that the hardest part could be WvWvW, I must change my mind, it is really hard, due to the team colour allocation of servers...
Being more specific, I'm on Whiteside Ridge and it's like since 2/3 months that I go to WvWvW at least once a week, to be sure to catch up every new match, and so every new colour... but we never been (as far as I started to do it) in the green team, making it quite impossible to break through enemy lands to complete my last map exploration.
So now, to the question, how is the colour assigned to the three matched servers? Is it statically given based on the leaderboard position? Like 1st, 4th, 7th and so on always green, 2nd, 5th, 8th and so on always blue and the other ones always red? Or is there a chance that even if the leaderboard will not change, my server could finally switch to green?
