Could MRD Possible Be The Best Melee DPS Class ? (Theory Crathing)

[Tiggy]

So I have!

125 x 1 = 125
250 x 3 = 750
375 x 5 = 1878
= 2750 threat generated

Same numbers with Defiance

100 x 1 x 1.5 = 150
200 x 3 x 1.5 = 900
300 x 5 x 1.5 = 2250
= 3300 threat generated

3300 threat to 2750 threat.

I'm not sure where you are getting the numbers from, but assuming a 1.5x rate with Defiance then it still gets more threat than not using Defiance.
