[2021] Behemoth's Glacial Quake Can No Longer Attack After a Slam.

Despite no mention in the patch notes, it seems that Glacial Quake has received a nerf, on top of the speed buff to shiver strikes speed. Last season, and the seasons before up to the introduction of Behemoth, you could perform another attack immediately following a slam; something you HAVE to do to quickly finish the target you froze. Now, all you can do is slowly walk into your enemy to shatter them. You can't even start to sprint immediately. This change doesn't feel good at all and it makes Behemoth feel like a really unresponsive Fist of Havoc.

Is this an intentional change that got missed or is it a bug that's going to be fixed in the coming weeks?
