I've actually been posting what I have posted with 30 to 35 people raids. Not 50v50 raids. And the OP is trying to prove that Darkrunner is the class that wins everything. I am proving him wrong because Darkrunner is NOT the reason raid v raid (30 V 30ISH NOT 50V50ISH) fights are won.
Yes, Throw Dagger can be combo'd with Whirlwind Slash to cause a trip to slowed targets (Whirlwind Slash always tripped slowed targets actually, it was just hard for melee to use it because it would require them to run Sunder Earth). That doesn't mean a Darkrunner or any other melee class can rock up to a mageball, use throw dagger then whirlwind slash and act as if they are fine. They will get their GCD thrown to hell and will probably have a hard time getting out of the mageball.
