I feel like you could go -1 nova + air tower, or -1 quantum tower +1 air tower. It just seems like 4 air towers as your primary source of air quanta, and 4 nymphs tears to eat them all up seems to be a little on the low side. I assume you probably wouldn't use all 4 nymphs tears in a game, probably 2 or so, but having a continuous stream of air quanta would be nice. Maybe i'm way off the mark here, what do you think?
