ArenaNet has announced that the next Guild Wars 2 PvP League Season will be starting on March 7th. Season 6 will run from that date through May 1st. One of the significant changes will be that, even if on the losing end of a match, pips will still be earned if 80% of the winning team's score is earned.
Participants will definitely want to check up on recent balance changes before embarking on a trip for PvP glory. You can do so on the Guild Wars 2 site.
