I suspect Yogg will still see some play after the nerfs. People seem to have looked at the probability of him eventually dying during his casts and concluded that he's useless every time that happens. In reality, he very rarely dies before the 5th or 6th spell, and that's usually good enough. If there was a 10-mana card that just cast six random spells and had like a 25% chance to also summon a 7/5 or whatever, that would get played. What you usually want out of him in druid is a board clear, so if you play him while your opponent has a number of minions in play, the odds of Yogg killing himself with single-target removal are quite small. Usually he'll die to a board clear and will have served his purpose. He's worse now, but not hopeless. For a class that has no other board clear, I think he remains playable.
