Most of Riot's champion reworks have been failures

And worse yet they very rarely do follow up changes to fix their problems or make them viable.

There are 4 reworks which i would consider to be successful.

**Rengar **- Hes competitively viable, good in solo queue and less overbearing than his original incarnation. Vikor - An overall improvement to a champion that had serious flaws, might need a couple tweaks. Skarner - Many people dislike this rework but i find him to be pretty strong and its an improvement over his previous kit **Xerath **- Somewhat controversial but i think hes a much better champion, has seen competitive play.

Now the failures

Karma - Ya old Karma was probably bad too, but new Karma isnt much better. Shes never played, and is generally just weak. She has received no follow up changes to speak of. She was supposed to be a mid laner i think, but is just outclasses in that role.

**Heimerdinger **- Overall weak champion, will never be competitively viable. His kit is just bad and doesnt work. His turrets are abusive in the early game and far too weak in the late game where they pretty much instantly die. His W is ok but the cooldown is too long, his E is extremely difficult to land and unreliable.

**Nidalee **- This rework is all around bad. Pretty much destroyed AP Nidalee, and made AD Nidalee overpowered. It shifted a huge portion of AP Nidalees damage in melee cougar form, problem being that if you go into melee range as a squishy AP champion you will instantly die. Her damage in human form is lackluster

**Master Yi **- Relies on Feral Flare to be viable. Basically didnt change anything except to give him absurd amounts of true damage. He is still a champion who has no counterplay and is extremely abusive late game if fed where he can basically instantly kill carries with no ability to react. Can easily solo Dragon at lvl 6 and solo Baron super early in the game. If he doesnt get fed on the other hand hes basically useless and liability to the team

**Sejuani **- Ive seen Riot employee's insist that shes a good champion or isnt bad, but this is simply false. Her clear speed sucks, her damage sucks and her mana costs are absurd. She goes oom clearing one camp. She has great CC sure, but it doesnt make up for all her weaknesses.

Sion - Might be too early to tell, im sure many people love him and would disagree, but quite simply his kit is too unreliable to be good. Hes probably pretty good at low elo, however his abilities are far too easy to dodge, particularly his Q. You will pretty much never land a Q agaisnt a decent player and his ultimate is way too hard to control and direct.

**Olaf **- Dont have too much to say about Olaf but hes pretty weak overall.

Soraka - I hate this rework, i think its terrible. Her heal range is extremely low and she loses her own health to heal basically making her a free and easy kill in any fights. She has pretty much no peel or cc for her team or adc. Edit **Cassiopeia **- Not super informed and ive only played her a couple times but as far as i can tell the main issue with her is that they significantly reduced the damage on her poisons and made her early- mid game weaker, while only making her strong in super late game where she can get her passive stacks up. Stacking takes too long/ is too difficult to do.
