Is riot ever going to address the horendous imbalances in game?

To be clear, I am not opposed to off meta builds, but this is getting out of hand. Champions have all been given such insanely high base damage that almsot every game i play now 4 of 5 champions are building one damage item then going pure tank because theres NOTHING you can do about it. I am so sick of seeing tank assassins, or overly tanky fighters, hell, even tanky ADC's like graves... Its not fair, its not fun. Rito has allowed their own game to become so imbalanced it actually makes me not want to play anymore.

Theres an easy fix to this issue too, thats the worst part. Riot has already prelabeled every champion in game with a primary and secondary role, so, why not have that mean something? Have all items in game have a base set of stats, example, 10 MR and 100 HP. Then, have every single champion in game have their primary and secondary roles impact how those stats directly impact them.

So, let's say i am an assassin/fighter. So, as an assassin my weakness is that i am meant to be squishy and easy to kill if i screw up, so items that give MR/armour/HP should give REDUCED amounts of the base value, say... 15% for primary role, 10% for secondary. So, im primary assassin, my 10MR 100HP item now gives me 8.5 MR and 85HP instead.

Now, let's take that same item and apply it to a tank, well its a MR/HP item, and tanks need those kinds of items, so it gives MORE then its base value for being used on its intended user, so say it adds 15% instead of removing it, so now it gives me 11.5 MR, and 115HP.

Finally, what if the user is neither tank, nor assassin? Well, the item jsut gives flat values, 10MR 100HP.

But wait, how woudl you balance every item in game? Well, easy, rito looks at each item and decides who its best suited for, or who its meant to be used on, then labels it as such. Or, write a line of code that determines what the items gives the most of (defense, offense, utility, etc), and apply that to the item, then determine which of those applies to each champion. Braum is a support/tank, so he should gain more HP from tanky and utility items, while gaining less damage from damaging ones.

And this is jsut a simplified, base version of the idea, I'm sure with a bit of work rito could refine the system, a system that allows off meta, or undesired builds to exist, but not be absolutely BS in game, like hypertank fizz, or tanky yas with 100% crit, or ADC's grabbing gage because it makes duels automatically fall in their favor... etc...
