Oz's Flame Gear after Jump?

Chaos changes: -


Warrior Jump changes:

So it changes to having a longer duration and decreased damage?

Chaos - 100%x8=800% every 8 seconds.
4000% every 40 seconds?

Jump - 40%x40=1600% every 40 seconds.

So does it get nerfed from Chaos or does spadow's jump description pertain to something else?

AoE DoT skills like Poison Mist, Flame Gear and Poison Bomb, are only good if they last for a (long) time. 8 seconds is too short for the skill to be usefull for extra DPS, since you have to recast the skill every 8 seconds, and that costs time (and lowers your DPS with it), time where you could have used your main DPS skill to do more dmg then casting the AoE DoT skill.

40 seconds AoE DoT skills are better by default, since you only have to cast them 1x per 40 seconds to get the extra DoT DPS.
