Dead titan gave up the orb, so now I am choosing who to level up.
Wu is ready now, while Leonidas and Chao are nearly there.
Is Wu all that much more one tier up? Way I see it (and I admit I meay very well be wrong) is Wu would be adding to card levels but not much will change with his special.
Leo seems to be just a big guy with a sword. The mana reduction is nice. Self-healing is needed because he is so slow.
Chao reduces mana, but not as much Leo. His best asset is speed.
Right now, I guess I would go with Chao.
A 10x holy pull is not out of the question here.
