I was testing out some new shizzle when i came across something weird...
i was doing LFR, did all 16 bosses, and got 16 loots.
Here's what i did;
1. Sign up for LFR raid(ungroupped)
2. Join it, instantly when the queue pops
3. Clear trash untill the first boss... i was always in the top 3 activity.
4. Pull boss, dps 25% hp away.
5. Leave Group.
6. Wait untill they've killed the boss.
7. locate a mailbox and loot.
I did this with every single boss, and got a loot from them all - I might just be lucky, but who knows.
