Hey everyone, just posting a little tip on how to get 4 easy mounts for Mountain O' Mounts. This may be common knowledge to some, but I have a feeling a lot of people may have forgotten about this place. This place, is Ahn' Qiraj.
Cutting to the chase, Qiraji Resonating Crystals (Red/Blue/Green/Yellow) drop left and right in this raid. Seeing as this is level 60 content, I went in there the other day with a friend of mine and was able to get all but the red mount (lower drop rate, also gives a different achievement for looting it) in a matter of ~30 minutes.
Hopefully someone can benefit from this, good luck with your achievement
