Most rotational guides indicate to open with dragonrage. Why would that be when the enemy is at max health? Wouldnt it be better to wait before using it?
Tyranny isn’t the only thing it does.
It was more important in season one to hold it for a bit, but the set bonuses we’ve been having make it function more like a normal DPS cooldown. Even in S1 you would not hold it if it cost you a usage, or if you were lusting on pull.
The season 2 set bonus made the obsidian shards always supercharged during dragonrage.
The season 3 set bonus makes damage ramp up through dragonrage, and then persist after it’s over. Combined with the fact that mastery is far less important to our damage profile now with the recent changes.
