I've just killed Lei Shen in LFR after 7 WIPES and guess what I've got after all this time I've wasted - a bag with 30g. It's great that Blizzard made this fight pretty hard in LFR but after wasting so much time I think I deserve something more than 30g. Lei Shen should always give loot or at least Blizzard should make those fricking bags more valuable - they should contain some usefull items or just give more gold.
