Just looked at my profile, and I have 21 LFR Lei Shi kills. Been doing it every week + charm, and some extra runs with just a charm.
Today I got my fourth (!) trinket (see
http://eu.battle.net/wow/en/characte...h/Tolgrim/feed ), I also have gotten the other two pieces dropped by Lei Shi twice each - no weapon, of course.
I know some raiders will say "well, it's just LFR, get over it..." and it's true to some extent. It just sucks that I'm quite far with the legendary quests and can't use any of the rewards...
