I'm an optimist. So when I had two Azure Whelplings drop for me yesterday, I was ecstatic and assumed a relatively high drop rate for the little bits of blue goodness. Oh how my classes in statistics and knowledge of randomness completely failed me.
Today, I spent some time in Azshara farming what I was hoping would be a good number of the whelps. Unfortunately, after a few very long hours of nothingness and over a THOUSAND mobs killed, it turns out that the drop rate for these little guys is much lower than I initially thought. Shocking? No. But still disappointing to those hoping to catch one of their own.
Mob info shows a drop rate of about 1% for the 3 that I picked up over the past two days. However, the data doesn't consider the mobs I was killing that didn't drop a whelpling. In total, the figure is about 1300 dragons, and with only 3 drops, that puts the drop rate at about 0.02%. Does that mean the Azure Whelpling is the rarest of the Tiny Whelpling family? Potentially, but given that 2.3 has only been live for 2 days, only more time will tell.
Happy hunting. =)
