http://us.battle.net/wow/en/forum/topic/6934366316Tons of people using bug to get into Heart of Fear and Endless Spring LFR, and seems theres no loot cd, the way is to have a guild 25 ppl raid, que for Mogushan Vault, telepot out, and ppl can walk in Heart of Fear or Endless Spring LFR!!
I thought the last time 4.3 patch Paragon did sth like this...This is EVEN WORSE!
