Actually, you did not nail where the problem lies. Shyvana's ult provides slightly less MR/AR, true. But her ult serves a different purpose: it provides effects (generally AOE damage) to all her skills, and allows her a gap closer/escape/knockback. Jax's ult does not last as long, nor does it have any of these other utilities.

Another comparison could be Garen's W, which provides him 25 free armor and mr along with a % dmg reduction. So no, you can't call Jax's ult OP.
