This is still happening. For example killing level 15-16 bats in Silverspring, one bat will hit me for 21, then bat right next to it will hit me for over 600 @.@. This routinely happens on the Silverspring map and happened on the Howling Mountains map.
Ostriches, wolves, spiders, kobalds...you name it.
At the time of this post I am a level 26 Knight in 16-19 level gear.
