Here are all tournament events sponsored by ArenaNet before the introduction of the Monthly Automated Tournaments (mAT). From Guild Wars World Championship to the Winterfest Tournament, there was a qualifying season with the reset of the guild ladder, and guilds had to finish in the top of the ladder (usually in the first 16) at the end of the season in order to be qualified for the season's playoffs. The single elimination matches were in best 2 out of 3 battles.
