I think you're over thinking things, Reyhart. It's very simple. What gives Law now, will give Eso in 3.2. Fractal will continue to drop i160 (or greater). You do not need roulette to run this. You'll be i170 in a few runs, able to do the Pharos and Abor which drop i185....and by then you can run an unlocked VA/Alex/Savage.....

And all of these dungeons will drop the new tome aswell.

I feel like you believe roulette is more important in gearing than it actually is.
