Ooh, you see the obvious, but perhaps they don’t — not only have they long ignored the gigasaur in the room, but also they are attempting (remains to be seen whether they succeed — perhaps their effort to deliberately replicate an atrocity they’ve inadvertently created earlier will actually result in a failure, as usual 
, to do even that; however, I’ve already contemplated celebrating the return to Un’Goro just like I did it back then — by quitting the game for years But that’s another subject) more of the sort:

.
Maybe if it wasn’t a card from one of their pet classes (the maturity of the team!) — Rogue, Pala, Druid — but from Mage, Priest, DH etc instead, they would have done so long ago AND increased mana cost to boot. But anyway, except for their fetishes, what’s wrong with adjusting such atrocities? I personally wouldn’t mourn it.
Such options have been obvious for some time, too, at least to this poster, for example: 32.2.4 Patch Notes - #21 by SparkyElf-2852 . 32.4.2 Patch Notes - #12 by SparkyElf-2852 (looking also at the patch numbers, hard to tell the difference ) — and it’s still the same tune, Sassy Feet defiling the ladder as usual.
