I like the new voice acting for the kill streak (a.e, Wrathful, Godlike). The only problem is the best one of all, in my opinion, was taken out at beta 3 launch, and that was, "Oh my Demigod".
I think it's awesome that you guys got Christopher Lee voice acting too now, maybe ask him to also do the "Oh my Demigod"?
I just think Godlike is too generic among dota typed games, it was nice to see something more creative to be honest. Obviously it's just one mans opinion though
