Anet may want to take a page from Planetside 2 and have unbiased GM’s patrol BL’s.
It would be huge for a GM to come in and MAP System tell the BL, I’m here for complaints. They would have tools to teleport [even below the map], be invulnerable, be invisible. Issue Account bans on day(s), weeks, entire rest of a season.
A 3 man team to cover 24 hours could cover multiple 3 server match-ups at a time.
