To start off and make sure I'm not breaking any rules, let me please state I'm neither looking for an opinion on which does more damage, nor asking which one is more fun.
I'm coming back to legion after a break and after mainly playing ranged classes, decided to give melee a better try. Based on PTR/YouTube I've narrowed myself down to either an UH DK or a Fury Warrior. From what I can tell right now, both are very fun plate wearing melee classes with good potential for both ST and AoE.
What I'm looking for feedback on from anyone who has done some higher content in the beta, is what separates the two in a raid or mythic setting. Is DK lack of mobility a problem? Is Fury lower survivability a problem? Are they equally good at swapping targets/burst windows? Does one have better raid focused artifact talents, or have CDs that work better in raid/mythic environments? I'm completely indifferent to DPS and even legendaries, because anything could be nerfed or buffed at any time. I really just want to hear about some advanced mechanics and "potential", and trust the damage will sort itself out.
