Why can't we dust him for the full price ? We want our dust back.

We probably won't receive it, but people are right - this technically is a nerf so we should get a dust refund. Of course it's not a nerf in a scale like to Rogue Quest, Murloc Warleader or any card nerfed, but still - they changed it for worse, so it's a nerf.

You're an idiot

It's a "niche" nerf: the basic mechanic of the card is unaltered, just limited in a way that rarely impact its effect. More like a fix than a nerf.

This isn't a nerf. The only way that the change to the animation would affect a player's play style is if they relied on the fact that Shudderwock would eat their opponent's turn, thereby winning that way... If so, then that deck is exploiting a bug. They fixed a bug, but kept the nature of the card intact.. Not a nerf. 

Reducing the animations time isn't really a nerf, true. It just makes it less annoying. But putting a limit of 20 max battlecries does look like when Yogg-Saron was nerfed, without changing the text but a significant change in its effect nonetheless.
