To be honest, we don't Need one.
Warrior and Paladin do not Need (and should not) to be the same in everything and right now the only class better then Paladin when it Comes to generating hate on multiple Targets is Warrior (and thats ok).
Flash an CoS is enough for us we can easily hold aggro for groups.

I would rather have a finishing skill for riot blade as well as some defensif buffs for the whole Party similiar to cover. And if I understand the Benchmark Video that is what we get (at least I hope so).
