BRF was released WAY too soon, most guilds never got Mar'gok down on mythic before BRF came out, based on what they're saying, it look there will be tier split between Emerald Nightmare and Nighthold, That will be the first tier, and they will space out the tiers so they aren't so clumped together and then a year+ drought at the end.
Perfect news, couldn't be happier.
