I would love to see a return to the original niche design that made DKs awesome - the ability to tank/dps in any spec.
“But they tried that and it didn’t work” , you say? Well that’s because they did it wrong. Here’s how it should be done:
NOTE: For simplicity sake, let’s assume that a DPS spec is meant to do 2x the damage of a tank spec, but also takes 2x the amount of damage.
Decide on a DPS output that you feel is a fine baseline for a tank. Design the attacks and buffs such that if a good rotation is sustained, this is the amount of damage it will do.
Now, you need two auras. One aura is for DPS (Onslaught Aura), the other is for Tanking (Domination Aura).
When Onslaught Aura is active, all damage is increased 100%.
When Domination Aura is active, armor class is increased by xx%, health is increased by xx%, threat generation is increased by xx%.
Blood focuses on leech and bleed effects. Self-healing and DOTs
Frost becomes a control spec, with slows, spell blocking, etc.
Unholy focuses on diseases using strikes and spells to apply several diseases to targets, then casting epidemic to cause all of the DK’s diseases to spread to other nearby targets.
“But…”, you say? No. Just no. No this doesn’t cover every “what if” possibility. It’s a design scheme. Just think of the possible.
