Emberwake: Not stacking ignites correctly?

After dozen of tests and discussions, I've come to the conclusion Emberwake does not stack ignites on my build.

I'm using Emberwake + The Taming with Molten Strike + the 2 threadshold jewels with Oro's Sacrifice.

You can check my profile: char:= Asymat_Legacy_Two

Chance to hit: 100%
Chance to ignite: 73%
Projectiles: 7
Attack speed: 4.59

The dps feels constant on a window of 6-8 seconds (couldn't test longer) while I was expecting a huge ramp from both ignites dps (double dip gem + fire/elem damage) and the taming (very little increased damage in tree).

Feel free to ask me anything or any test I could run.

So far nothing that I have tried have shown any change:
* Swapped weapon (Dyadus)
* Swapped position of rings
* Different gems.


I really hope someone gonna find the mystery or the bug gonna get corrected. I cannot wait to triple my dps. :)

[Case closed]

I'm igniting so many times allready, I reach my close to max dps in 1sec. Ignite dps is very negligible.
