If you do the naga ore quest in a grp, which is what i do with my resto shammy, be careful. If your partner picks up more than his 3 keys which happened to me, the keys wont drop anymore. I had 1 key and he had 5. we killed for 30 more min and the keys wouldnt drop. So i left the grp and just tag them and he would kill them, once i did that it only took 3 kill to get the last 2 keys i needed.
Clearified:
-In a grp
-Naga ore daily
-Group loot is on
-Your Partner pick up more that 3 keys
-The Naga will stop dropping the keys once your grp reaches a total of 6 keys dropped
-The keys are BoP so your partner cant give you them if they accidentally pick up more than 3.
-Leave grp if partner picks up more than 3 keys.
-Kill solo
Hope this saves people a lot of time ><
