They had to have known that some of these game breaking problems would rise for preseason.

I GET that preseason is a time when balance is out of sorts. that's the fun of it. It brings out tons of changes that they gradually fix that shape the next year's season. But goddamn, some of the stuff we're dealing with right now, they HAD to have known it going to end up bad

Warlord's bloodlust. It didn't take a genius to recognize that this mastery would be blatantly op on a couple champions (looking at you, yasuo and tryndamere). Those two are ALL ABOUT crit, you MUST have known it going to be a problem on them. there's just no way you didnt. So why didn't you tone it down before it hit live?

Deathfire touch, same thing. You MUST have known it would be broken as hell on dot champions. Brand's become a frickin monster. He's bad enough in mid lane, but he makes bottom lane literal hell on earth.

Going slightly off track:

Why have we not addressed Tahm yet? we've known for a while now he is by far the most toxic champion to play against by taking anyone out of danger instantly, his absurd amount of tanky-ness with his e, and his insane damage while building health because of his ult passive. He's Waaaaaaay too strong on those who know how to play him, so why are we still suffering at the hands of this overgrown catfish?

Fiddlesticks is still shit tier. Fun fact: the only champions who are ranked lower then him on jungle performance are junglers who's primary roles aren't even jungle. Through repeated nerfs coupled with the final nail in the coffin - the switch from magus to runeglaive- he might as well be an inanimate scarecrow.

Returning to the main point:

everywhere you went about PBE talks prior to the release of 5.22 said that graves was a 100% ban every game, god forbid we change that all. Because, let's face it, we all love getting our faces kicked in with 20 pounds of lead.

The problem isn't essence reaver. while the free 30% cdr is nice, cdr has never been the primary or even secondary or tertiary stat that adc's want or need. Only Lucian, Graves, and MF are rushing it first item. It's a good item and a nice pickup on the champions it works well with. The PROBLEM is that the classes the actually utilize cdr better, mages and ability-based fighters like garen and irelia, DON'T have easy ways to build cdr. For mages, after athene's or morello's, unless they have cdr runes they're stuck at 25% (yes, you go 18 INTO CUNNING, NOT FEROCITY ON MAGES), which is not nearly enough. I'm glad we thought up ways to give cdr to the role that doesn't really need it, but completely ignored the class that does. This hasn't been a new problem either. Ever since the removal of dfg from the game (rip dfg), that extra 10% cdr you got was what I truly missed.

So how did we forget/ignore all of this. Just what happened?
