He's a strong jungler insofar as... he won't die in the jungle unless there's some awkward duel and a bad WW doesn't realize he can't take red buff with 10 health or something. Aside from his safe jungle, he's not good at all until 6, and then he's one of the slower junglers to top it off. If his jungle gets interrupted, it's extremely bad news for WW-bb. :< (He shares this problem with Shen-bb)

A good jungler to learn for beginners would be Udyr or Dr. Mundo, maybe even Trundle. While mechanically they aren't WQQQQQQQQQQQQQQQQQQ (as easy), they are at least "better" picks than Warwick. (In Blind Pick solo queue)

Yes, which is why learning to jungle first with WW is just a bad idea. Once WW blows his load, you can pretty much ignore him.

I think learning to jungle with someone who has natural sustain is a bad idea and all the champs you've suggested are tanky to boot. I pretty much agree with Stonewall saying Jarvan is great for a beginner ― he doesn't have an amazingly fast clear time, his item build will depend on the enemy and what his team needs, his stand/flag is like a mini-ward and he can also gank in different ways. I don't know anyone else who can go from that cliff straight down to river bush. Fizz is like 2~3 Teemos away from being able to do it iirc.

Situation situation situation. :/ I mean, he is in fact a strong laner because of his sustain (especially once he gets a few ranks into his Q), but again it's all about match-ups. Lanewick is stronger than Junglewick right now because the new jungle is about getting through it asap.

Oh, that's not what I really meant. It seems to be very difficult for Lanewick to come back if he gets destroyed at top since he's a bit slow at clearing waves. At least Lanedyr is tanky, but I wonder how WW would have done if he tried that.

Garen would be a good starting character if it weren't for the fact that he falls off at level 1. Exaggeration yes, but unless you get ultra-fed, you're not much help to your team. Unless the team comp involves all the stuns in the world for spin2win. Sucks to suck for Garen-bb.

What happened to situation situation situation? （*/∇＼*）

Early-game champs are great for people learning the lanes! Lower level elo is all about stomping your lane and damaging the morale of the enemy team. Unless you're Teemo because everyone just wants to kill you for some weird reason.
