Mastery overhaul Idea's

So a bit of a rant coming but bear with me here.

I think the current mastery system sucks! There i said it!

So what exactly do i think is wrong with it, well half the masteries are worthless and the other half are completely bonkers for starters, OK maybe not exactly but there are some bonkers masteries and some which are useless.

That being said, i didn't really want to talk about the balance of these masteries because we all know there are issues there.

No i want to talk about how some are put in the wrong tree. Like what is a sustain mastery like warlords doing in a damage tree GTFO and move into the sustain tree will you. And maybe Thunderlords can now walk over nextdoor into the damage tree. OK i hope this conveys the idea.

And we need a new tree imho, so then we have 4 yes, don't panic its just 4 not over 9000. The 4th tree would be a fully defensive tree, and then we would have something like,

Damage/Utility/Sustain/Defense

There can be some overlap like how Strength of ages can stay in the sustain tree because it gives a lot of sustain. But now this tree will also have Warlords and Grasp. utility would lose Thunderlords but gain bond of stone for protecting allies for example. Meditate and Swiftness could swap tree's as well for example.

Defense tree would gain a few power full new keystones for protection vs damage or other stuff which involves the soaking of damage like gain a speed boost for absorbing X amount of damage. Masteries which will amplify defensive builds or grant bonuses for being able to absorb damage etc etc. Might even gain some old masteries back like adaptive armor i miss that one ^^

And finally once this is all organized i want keystones, especially the final tiers to be more widely usable so there are good options for every champion. This could require changing the way some keystones/masteries work like turning Warlords into omni-vamp for example, although i am not sure if that's a good idea, and perseverance giving a good flat amount of regeneration so its good on both mages and tanks for example. But don't get hung up on the balance of that its only some ideas i just brain farted out.

End of rant

Ps: If you have any awesome ideas(or simple ones) for tank masteries please do post them.
