That DK Dual Wield Frost sim is laughably inaccurate.

I don't even play a DK. This is just something I was messing around on. And I'm pretty sure the result of the DK changes the other day are a pretty huge gain in DPS... so... nerfs incoming I would presume.

Actually, melee as a whole needs to come down, and specifically needs a myriad of nerfs for PVP. Casters are literally retired if PVP goes live anywhere near the state it is on Beta right now. Melee do more damage, have 50x the mobility, low-CD interrupts.... really, you're just bait as a caster in any pvp situation.
