Is it just me, or has Riot REALLY been abusing the game lately?

Cinderhulk

Sated Devourer

Zeke's Harbinger

Luden's

And what's more, every time these things are deemed to be overpowered, they either take months to nerf them, or they don't nerf them at all.

So not only is there a huge amount of insanely crazy balance decisions, it's also combined with the fact that they aren't bothering to tone them down. There's a HUGE DIFFERENCE between "Okay, let's just take a step back and assess everything when the smoke settles" and "Gee, this is some great fan art. -checks watch- Only three more years before I have to nerf Cinderhulk."

Also, slightly unrelated, did anyone notice how each of the above items buff every single role in the game (Cinderhulk = Tank + Tank jungler, Sated Devourer = Carry Jungler + ADC Vayne, Zeke's Harbinger = Support and ADC, Luden's Echo = AP) except assassins?

I have been playing this game for over four years and never have I seen Riot stir the pot up to this extent.

Keep in mind that I'm not the type of person to think that any form of change is automatically a bad thing, but Riot has been going waaay overboard. Understandable, since this is the first time they've been going so insane over balance changes, but I don't think they should have started all this crazy shit outside of a Preseason (they only began creating these ridiculous items and refusing to nerf them during the second half of our current season).
