2. Click on warrior/mage talents.
3. Read their respective talents and check over what amount of time the damage is spread.
4. While reading, check what abilities make those talents work.
5. Answer your question yourself. It really isn't hard.
If you can't
Firstly both ignite and deep wounds do a ton more damage because their percentage values are much higher. Second both of those talents proc from various abilities which makes their stacking both faster and bigger. Thirdly their damage isn't spread out over 10 seconds but over 4 or 6. To compare,
1,000 damage:
- over 10 seconds = 100 damage per second
- over 6 seconds = 166.6666666666667 damage per second
- over 4 seconds = 250 damage per second
