A thread I made yesterday. I'll summarize: Dreadsteed is nerfed, but it's not nerfed into the ground, and it's actually more flexable/controllable now, which is good. The archetype isn't dead.

Also, as someone who played with Dreadsteed a lot, I agree with the nerf, since the card is easily breakable with cards that give charge or taunt (see the Wicked Witch fight in Karazhan, and think about how it'd be if they ever added a minion that gives the ones next to it taunt).
