A thing that's bugging me out when seeing ways to try to help tank junglers, and seeing masteries

So people wanna improve quality of life of tank junglers. Unfortunely many of those ways also benefit non-tank junglers. Also, some people already are saying (and correctly) that some tweaks like to jungle (like nerfing Heavy Hands, as r/user/ElixR mentioned on reddit once) also hit a lot the tank junglers.

I was seeing the mastery pages (and yes, I know Riot Meddler already said no changes were going to be made to masteries), and I wondered, why the only points that help clearing the jungle on defensive tree are on the 1st and 2nd tiers? I just ask this because those points are also easily acessible by offensive junglers, and that's why those points aren't very strong.

My question is, why there isn't a stronger mastery point for junglers on the defensive mastery tree, on 4th and 5th tier? On the way the points are now, you can't really buff the current points too much, because that also benefits "carry" (just used as a non-tank term, that's why I used the "") junglers with their usual 9 points on defensive mastery.

I mean, think about it, if there really was a true mastery point on higher tiers of defensive tree, it would be no problem if that mastery was indeed stronger than the current ones, because since it would be on the higher tier of the mastery tree, it would obey players to choose, or go with an offensive mastery display, or with a defensive one.

The current problem in my honest opinion is that, while defensive mastery page is indeed strong in game overall, it isn't as useful on jungle as the offensive mastery. I mean, damage is damage, is always good if jung centered or "global" centered. It's still a damage boost. While on the defensive mastery page, they aren't as overwhelming as offensive masteries.

So in my opinion, I believe a strong mastery point on higher tiers of defensive mastery tree would benefit tank junglers. That's what is lacking in the jungle scene in my opinion to benefit tank junglers. They lack mastery options for the jungle, even if they don't lack for the game globally.

I won't give ideas of what kind of mastery it should be, I fear that I could mess up on the balance way, but I believe that puting it on higher tiers would be nice to help them out.

Let me hear what you guys think of it, and if you don't agree with, discuss it, it's always nice to talk about new ideas, being good or bad :)
