A win rate of >50% against FGs?
As much as I love Aether (I'm one of the four candidates running for the next Master of Aether position), there's no way that upped mono-Aether can do that, much less a partially upped one.
Permanent control and momentum ruin your day, and a few of the FGs that have neither will still manage to outrush you before you can start chaining Phase Shields.
You might still stand a chance against the less difficult ones, but pulling off a 50% win rate is nigh impossible in the long run. I would say that ~15-25% is more realistic.
If you really wanted to use it, then I recommend splitting the Towers into 50% Towers, 50% Pendulums for Earthquake resistance, and adding in another Lobotomizer and a few Shards of Gratitude if you have them handy.
