Why are people so negative about some new animations?

Wowhead published an article about an hour ago about new hunter animations on the 11.1 PTR. People in the comments out there saying it's a "waste of developer time" or that "old ones are better" when the old ones were clearly more generic and less discernable.

I get the Colossus Smash/Warbreaker update being... weird, new Shaman's Lightning Bolt animation not being much of a lightning (but it's still better). These two are fairly valid complaints, but people are describing some of the new HUNTER animations as "needless visual clutter" when they barely have any even AFTER the new update??

There are so many outdated animations and i've spoken out on the issue of visual consistency in WoW for years now myself, it's just super weird when Evokers and Warlocks have super detailed fire, meanwhile Fire Mages have this 2015 "HD" look to them.

Are WoW players this afraid of change?
