I don't get why Riot is so intent on releasing more champions while existing ones remain mediocre

Like at some point they have to take a step back and think: #ONE HUNDRED FORTY EIGHT CHAMPIONS I'd say we've created more playstyles and character options than anyone else, maybe it's time to slow down on creating more and start actually balancing or really doing any sort of noticeable work on the existing ones?

And it's especially bad when all the existing ones get so outclassed by these new shits that all come spoiled with effect after effect spewing out of every deign corner.

Like ffs just look at She's a stacking champion who is infinitely more powerful than all other stacking champions

Gets increased damage on his Q Gets increased max HP from kills which makes his W value bigger Gains AP and Armor Gains AP and CDR on his W Gains attack damage, increased Auto attack range, increased ability range, crit chance, life-steal, and double dipping ult benefits where her damage is increased by each stack along with the shielding value.

She is so unforgivably over-statted compared to all other stackers who have to work their asses off getting hundreds of stacks to be effective. And the miserable part is, Riot isn't going to nerf her, no why would they after releasing her like this? No they're going to just power-creep everyone else eventually. It's what they've been doing with every single Rework and new release.

Let's throw %HP damage here, true damage burst here, multiple abilities in one here, give em three or 4 passive effects in their essay long Passive review as well as more on their basic abilities, and so on and so forth, They need to stop escalating things and take more time fixing the problems in the game 1st. We have 148 problems in the game right now Riot, we don't need that number to be 175 with not a single one worked on a single bit by the end of the year.
