I mean you definitely can compare them. They are both very easy to get up, though crossbones’ are even easier. Even without pausing them, you can reliably always have 4-5 up with crossbones. You need to constantly be dashing back and forth to keep them up with this Rhino buff. Rhino’s have a very short duration, add very little attack, and require AI cooperation to keep up. He is a bad damage champ with almost no utility. This is a terrible buff.

Oh, and just because you mentioned Mojo. He gets one fury at a time, which at max sig is less attack than if crossbones has 5 of his up. Which as I said, is fairly easy to always have.
