Sneak peek of the new Thief and Pirate

The main dps decrease would be the the reduction of the effectiveness of % boss damage on dualblades.
Right now, having 30% boss would make your regular hits 1.3x as strong, and your mirror hits 1.69x as strong.
After legend , it would only be 1.3x on mirror hits, which reduces DPS quite a bit.

 With 30% Boss

Pre-Legend
MI = (1.3*1.7*.7*40+1.3*.7*50)/90 = 1.19 + 1 = 2.19
630 * 1.67 * 1.3 * 1.178 * 1.135 * 1.19 = 4004.84%/s

Post-Legend
630 * 1.67 * 1.3 * 1.178 * 1.135 * 1.7 = 3108.78%/s

% Change
-22% Damage

 With 60% Boss

Pre-Legend
MI = (1.6*1.7*.7*40+1.6*.7*50)/90 = 1.47 + 1 = 2.47
630 * 1.67 * 1.6 * 1.178 * 1.135 * 2.47 = 5559.24%/s

Post-Legend
630 * 1.67 * 1.6 * 1.178 * 1.135 * 1.7 = 3826.19%/s

630 * 1.67 * 2.8 * 1.178 * 1.135 * 3.57 = 14061.27%/s

Post-Legend
630 * 1.67 * 2.8 * 1.178 * 1.135 * 1.7 = 6695.84%/s

-52% Damage

Looking for someone to check my math.

It doesn't really seem that bad for me, but, then again I only have 30% boss... for now. I would've compared Pre-Legend 30% to Post-Legend 40%, but it didn't seem like a fair comparison, if you're not willing to cube after Legend.
