Well, Morello has had to apologize for the state of jungle after literally every season. So I don't really give him credit for it after like the 4th time. And the thing is that hes actually getting worse at doing these things. He wants to increase diversity, and diversity becomes worse than ever. He has an explicit goal of farming junglers, and its probably worse than ever at many levels. At some point you have to just say that whoever is in charge of this at Riot is just not competent at balancing jungle.
Anyway, I'm not against the itemization changes. The current jungle itemization is hardly good, so it will probably be an improvement. I don't have real confidence that the supposed additional levers will help them with balance though. I mean, Cassiopeia was redesigned with the explicit goal that her new kit would give them more levels to better balance her. How's that going? Same with other champs that got dumpstered worse than ever like Skarner.
But the problem is the early game nerfs to junglers that are incoming. The old deal with jungle is that junglers don't get a lot of gold, but they get a lot of control over the early flow of the game. That sounds like a fair trade. But, if they "knee cap" their early game control, what is the point any more? Oh, now junglers can screw each other over with counter jungling? Yeah, its still a gold starved role that can't do anything other than screw over the other gold starved person on the other team.
But I don't think that Morello really gets this. If you take away the one thing that junglers get, you have to give them something HUGE in return. But I really doubt junglers are going to see big gold increases this season (junglers rarely do). So junglers might very well just end up as gimped carries. So why no just play a carry in lane?
What needs to happen if they actually want to fix things is they need to identify the real problems and actually address them. More items are fine, because they do give more levers, but more levers don't mean anything if you haven't spotted the real problems. For example, lets talk about diversity. Why don't you have diversity:
The biggest problem right now for most junglers is defensive itemization. You simply can't play a lot of junglers because building the items that they want is dumb. Those defensive items suck compared to the offensive items. A damage dealer with Zhonya's will survive almost as long in a teamfight due to the active AND deal a lot of damage. People ask me why I build damage on Amumu. BECAUSE BUILDING TANK IS STUPID. Its really bad because you just don't survive for long anyway - but toss+ult+Zhonya's is really strong. I mean, Sejuani has become kind of popular in higher levels of play. You know why? Because people stopped building her tank and went AP assassin.
I haven't seen any major announcements that this is going to be fixed, and I don't see any way that its going to be fixed just by having a defensive jungle item. If that defensive item is strong enough to try and make up the difference, everybody will just buy that item (like in League of Warmogs days), so it can't happen.
The second problem is mobility creep, which is just death to so many champions. Immobile champions can work in other locations sometimes because they might have range +damage. For example, Syndra has extreme range, utility, and damage. So that makes up for her lack of mobility. But junglers don't get those things typically, so they just have been screwed by mobility creep. But Riot is just making mobility creep a million times worse by introducing champions with kite kits (this new adc), slow kits (Braum), or kite+slow kits (Gnar). So not only is Riot not fixing this problem, but they are willfully making it worse because they want to release cool new champions that don't suck, but can't figure out what to do about mobility creep.
(Of course, professional play is a whole other can of worms with respect to diversity since they have very different requirements for successful junglers).
Anyway, these issues have to be fixed first. You can't just give junglers more gold. Otherwise, they will just use them to build more offensive items on champs that don't have problems with mobility.
