Prof. Warren (cool name, btw): they're alternating arcs. Ottley is definitely the type to finish an arc that he's on, and he's solicited until #5. Looks like Ramos is on after that.
For the others who don't like Ramos' style: I get it. He's not as precise or as anatomically correct as most. But dang if his artwork has that energy, vibrancy, and sheer fun that fits with Spider-Man and his world!
