That’s nothing new. Even during the days of Ben Brode (don’t wanna repeat myself yet again, so I leave the link for reference) they attempted to ‘fix’ cards like the Undertaker by waiting for it to wane and printing even more ridiculous cards, e.g. from GvG.
Remember how they ended Denathrius’s reign? By printing Astalor, so that people would forget about the former king, and doing a nerf when it was no longer relevant. Compare also Theotar to Patchwerk and so on.
Besides, if you look at the Mythic Boss Rush in Mercenaries, it has never been balanced well, but even if they cared, what would they care if it lasts for one week anyway…
Assuming that they read and care? Isn’t it a bit bold? 
(Highlighted by me) Exactly!
