What I proposed was the AI to spawn Nymphs on its own side until Water Nymph numbers reaches a certain point of which then it splits its task of spawning Nymphs on both its side and your side until targetable pillars and pendulums reach a certain number. AI spawning creatures, already, keep spawning creatures even if Flooding is out, so the AI doesn't care of the opponent strategy, for now.
Also, of the 12 Upped Nymphs, only Aether, Air, Darkness, and Time have attack which is greater than 5, and Fire and Life being the other two which can raise their attacks to 7 and 12, respectively, after a cooldown and extra quanta. The other 6 Nymphs have little use after the quanta denial. Eternity is not the only pair with this. Nightmare Nymph holds hand denial, Earthquake Nymph becomes much faster, Antimater Nymph for those higher attack Nymphs, PU/SoR Nymphs for hysteria in Top 50(0), A Duo Death/Flooding fodder/denial creator; possibilities are out there >.<
