Per Cayreth's original message: http://us.battle.net/wow/en/forum/topic/14882118713
Garrosh has a guaranteed heirloom drop between now and WoD (http://us.battle.net/wow/en/blog/163655 ... 10-14-2014).
Join us this Sunday as we clear the second half of Siege on Heroic (old Normal). We will start with Malkorok at 9pm EST / 6pm PST and expect to get to Garrosh by 10:30-11p EST. Due to the new flexible scaling of all non-Mythic raids, you are welcome to join us at any point during the night, assuming we're not already at full 30 people.
Whisper me (BattleTag: Cayreth#1709) or Hegel (BatteTag: Rose#1862) for invites.
NOTE: Due to the probability of a third of the raid being filled with Mythically-geared Indelibles, we are NOT setting an iLvl requirement for this raid!
