Just tried out the new jungle - its awesome
And totally different from anything that we have now. Hard in the beginning, especially for tankier champs who have a hard time clearing now, but with all the little minigames involved with it, you can totally do it. Naut can still jungle, he'll just have to start out at gromp to get the poison armor and then go to blue. Idk what kind of smite item he would get, but then he'd go juggernaut for the health and CDR.
One thing; this jungle, even as super different and mind-boggling is, reminds me of the S1 jungle. And Warwick is back to his old self. Other champs might have a hard time, but once he gets his smite item, he can clear pretty fast if he levels his W, insanely fast if he smite the golem thingys, cause they give execute damage.
Dragons are actually important at all stages of the game, the baron buff is insane and stalling is going to be nigh on impossible, the river creep should be a duck, but beyond that it is actually a pretty important strategic goal, and the still water buff is great for split-pushers. There is so much change, i cant freakin wait.
Plus, most likely the new SR is coming out at the same time.
