2318122:I'm betting that Vashj/Savin/Morova is as common as dirt.
I don't like Morova.
1) I'd rather play the Boots so Vashj is self-contained. Having to keep her next to Morova for her to be efficient seems... bad. Obviously if you play Morova you won't play Boots.
2) Vashj/Savin/Ta'zo's optimal configuration is the line. Vashj/Savin/Morova's is a triangle, making it more susceptible to Flamestrike. Which is why I'd also love Ta'zo for the mirror. Massive AOE + potential tick up your team?
3) Morova has range 2. Ta'zo has range 3, the same as Vashj. You don't have much mobility because of the Savin mana battery. Improved range is a must.
4) Arcane Flux improves critting odds better than Mark of the Wild, plus you'll already be playing Wrath of Air anyway. Also, WoA improves your two magic users, instead of having to wait until it Recharges.
