Pvp Skill ?

[Carcinogen]

Still, less damage

lol srsly? lets do the math here.
Mind wrack is a 1 tick skill with 15-25 damage on level 6. It has the most damage of all the skills sure. But Flames are much better preferred than Mind wrack. Here's why.
Flames of Insanity is a 3 tick skill with a damage of 11-12 damage per second on level 6. Wrack is a 1 tick skill, while Flames is a 3 tick skill, which will result in much more damage.
Total?
Mind Wrack Damage total: 15-25
Flames of Insanity Damage total: 33-36
With only a 2 second cool down difference. But Flames result in a much higher damage than Wrack.
Plus, there's a chance to stun on Flames. It's not even a small chance either. Since the chance increases as the skill level increases, there is a good chance of stun.
Both have a steady chance of crits. But think about it. Flames is a 3 tick skill, which means it's possible for more than one crit. Which will result in much more damage!
True, Wrack is an instant skill, while Flames is a bit slower one. But it results in a much higher damage result.
That is why Flames of Insanity is preferred the best over Wrack by many people, including pros n vets.
