How would Frozen Mallet work instead of Randuin's Omen? Personally, I think whatever tanking bonuses the Omen gives Vayne would be much less valuable than the takedown abilities of Frozen Mallet (though, the latter makes her less useful in team fights, something she seems to be struggling with already).
