Key drop rate

Sep 17, 2012
I really enjoy the new obsidian boss fights. I am happy we have some cool new additions to the game. I am concerned about the key drop rate though. I have been farming the level 55 mobs in aquila and have only obtained one key after 2 hours. I guess I would just be disappointed if it takes like 4 hours of farming per key... I just want to play the bosses more. Am I just wanting the game to be too easy? I wonder what others think. I really want to play the new content but I cant if they wont drop any keys...stingy
