PRESEASON JG: Sustain Junglers Vs. Non-Sustain Junglers

So about 6 months ago i started playing jungle as my main role, and I was starting to try new champions in the jungle squishier ones because with the right set up you could manage it; however about a week ago with the update my hope and dreams were shattered. I thoroughly enjoy Kayle jungle, to have your laner just go completely mad on their laner even losing the trade, then I come in ult and clean up... it's beautiful. With the changes to the jungle I struggle to be any sort of helpful at all, until 15 minutes in with kayle, and that has made me sad. So kayle obviously not being a sustain jungler, struggles greatly in the jungle. I also main Udyr jungle and granted I have a much easier time with him than kayle, I still find that even he struggles to get going. Along with taking away Madstone Build....UGH.... I feel that the monsters hit so much harder its really quite difficult have strong lane pressence and farm well since the changes. I just feel that the changes to the jungle are going to sincerely put a damper on non-meta junglers almost to the point where they are unplayable, was this even a concern in the Preseason jungle changes, or was it done on purpose to push people away from off kilter junglers like kayle, Vayne, etc.?
