These are extremely arbitrary criteria and not in the slightest way representative of everything a jungler's role encompasses.

There's exactly three competent junglers that have invisibility in their kit, and that's, and. actually happens to meet all four of your attributes too ( can tank the monsters for him, giving him pseudo-sustain, and gives him huge damage against any target, allowing him to wreck buff camps). Hence, is too strong...?

is a niche jungler at best. He has an average clear speed because of his very long cooldowns and his Q isn't enough to sustain him in the jungle. Building lifesteal doesn't contribute to his score since every jungler can do that. Sure he can gank really well, but if you really want to do that with him then stick him mid and have him roam. There's just all-around better junglers than him to use.
