Still it's been said by numerous vet fighters Spidey's unpredictable fighting moves are imperfect, he has gotten hit by lesser beings than him in strength and speed and tagged out of the air with bullets even with Spidey sense. He would benefit from learning to master his vast potential with acrobatic speed and agility if he had a stronger foundation with his reaction timing being focused instead of reactionary.
Spider-Man fights people like Wolverine and Deadpool, which from a stand point he can't afford to treat lightly. And Kraven has proven that Peter is not as good as a fighter on a metahuman with superior fighting ability numerous times. Only just edging out due to his Spider sense and being really flexible.
WOTS shows me he could solo any earth hero in h2h if he mastered the martial art. He could stand toe to toe with the Inheritors for once and some asguardian warriors.
