Sure. I think that printing answer cards is particularly hard to do in this case because a lot of the problem with WE is on turn 1. Contrast with the Shrine issue, where the game typically goes long and you have plenty of time to draw into answers before the damage is done. Also, as ddm pointed out, a hate card would have to be absurdly powerful and I'm not keen on silver bullet designs anyway.
I do not think that Eric has any input on design these days - last I heard he was working on social network games at a different company.
So yeah. I say revert the Shrine to its actual text, restrict the Warpstone and let's see what happens!
