Replacing Towers with Pendulums of the respective elements would be a good start -- it's going to be very difficult to power Quints and Fractals on just a Mark of Aether.
(I'm assuming that you meant Pendulums but put down Towers instead?
)
Actually, i tried both ways, but pendulums are frustrating. Those Nymphs need a lot of quanta. Fractal needs a lot too.
A pity there is no pendulum that is independent from mark.
Maybe you are right, though, and there is an optimal pendulum/pillar combo.
It would be better if there is a photon producer, maybe i revisit this idea once that's a reality.
