Given that barbarians have seen some love, what would it take to make them strong like they should be.

I have seen some talk about adding more dr, more prr, etc.

I think some tier 5 rage based +1 crit multipliers at all times while raged would be good.

Also I think Rage should have some effects based on barbarian levels 12, 16, 18, and 20. At each of those level ranks, it should cut the cooldowns for every cleave ability by 1 second.
