Hello dear citizen of warmane, is this a bug or not?.

I was thinking of getting sum cool xmog gear in upperblackrock spire.

So the last boss should drop duengon tier 1 set, the armor from warrior, druid hunter mage priest, warlock rogue.

i had the plan to get the shadowcraft armor which is 6.09 % droprate.

so i was farming this instance for 24 hours straigth, with minimal breaks.

Interesting enough it didn't drop any of the chests at all.

but i got drops on 1 felstriker 7 2handed epic sword which both have 1% chance of dropping.

idk if this is a bugg or not but it feels extremely weird that i get 7x 1% drop item before i get a 6% drop one :D.
