Can we stop pretending all the reworks are bad JUST because you dislike them, personally?
I've been seeing this a lot and it really kinda bothers me, so I thought I'd weigh in. In the wake of the Mordekaiser rework, I see a lot of posts that compare him to Cassio/Karma (mostly), but to whatever rework the poster doesn't really agree with. I'd like to share some things with you.
Before Karma was reworked (and then got her minor changes again recently), I regularly got kicked, trolled, or reported for picking Karma. Now I can pick that character and people will actually let me play it - not only that, but her kit feels more cohesive and requires a lot less reliance on her allies (you no longer have to expect the ally you cast W on to properly run it through people! yay!) but people still wanna talk shit about Karma rework all day long. It was a godsend for that character and put her in a position where she could actually have numbers changes and have power moved around in her kit. Her kit on release was a hodgepodge and was very feast or famine - either you got ahead and the shieldbomb Q combo was doing tons of damage and wrecking people, or you were behind and did nothing (because all her kit did was basically damage, with a small bit of healing in there). Now she has utility, and can play further back without the stringent positioning requirements from her old kit. Regardless of what you, personally think about the Karma rework, it was objectively good for her (she was played in the LCS and it wasn't a troll pick! woo!)
Before Cassio was reworked, we had a "poison mage" whose MO was to spam E. People act like this is new - no, that's always where Cassio's damage has come from. So they take an early/midgame bully who excels in skirmishes and falls off late and made her scale - the reinforced her poison damage (E increases the damage they take from poisons by up to 100% guys) and made her passive assist her in scaling into lategame which simultaneously hurt her early ability to bully people off waves. Regardless of what you think personally of Cassio's rework, she's in a healthier state in the game now. (And again, Cassio was only picked up in higher tier play AFTER the changes, not before.)
So when people say "Well of course they fucked up Morde, look at Cassio/Karma", these people are being ridiculous. What's happening to Morde is very different than what happened to either of the above champions. Cassio has NEVER been about the poison - her damage has ALWAYS, since her release, been loaded into her E resets. This is not a new mechanic. Karma's mechanic was ALWAYS about the Mantra - yes, the specific spell effects may have been nice and you may have liked them, but her theme was MANTRA, and they reinforced this with the rework.
Do I think Morde's rework was good? Not really. It needs some serious changes before it can be balanced, and it's definitely overtuned. But Mordekaiser's rework is an example of the few times that Riot -actually- screwed up, not just "screwed up" in the eyes of the community. At the end of the day, it's about game health, not your personal opinions. There are multiple other examples of reworks breathing new life into champions (Miss Fortune, Fiora, Garen, Skarner, Katarina, Evelynn [though that was short lived], Gangplank, and, yes, even Cassio and Karma). Just because there are a few where they miss the mark (Darius) and some where they miss the mark A LOT (Mordekaiser), doesn't mean that every rework forever will be garbage. And if you think that, maybe you're playing the wrong game.
