Damage conversion math?

Working on my Aether Deathknight, and I’m a bit confused on the math.

My instincts tell me that Aether Weapons is a better sword/ shield component then the seal that is normally used, but I can’t put the math together properly to prove it. I know that once your physical damage gets to a certain cut off ( where the 10% physical conversion is greater then the flat aether you get from Aether Weapons), and then factoring in the Aether percentage of 75% vs 55%, this is where I get lost.

I can’t post my build currently, but let’s just go with Mindwarp for the weapon and do the math based on just that. Any help from the mathamaticians?

very specific… :stuck_out_tongue:

you get 10% conversion also from wrathstone.
