Cass players get ready to stand for Sion players
Back in March of 2014 Riot Chun gave insight into a potential future retune of Lee Sin (http://www.surrenderat20.net/2014/03/red-post-collection-lee-sin-retune-team.html) which was to be similar in scope to the one given to Cassiopeia. Essentially, Riot wanted to reduce the early game power of Lee Sin and channel it into a stronger late game. This upset a legion of Lee Sin players because they viewed it as Riot attempting to pull a complete 180 on the power curve of the quintessential early game jungler. Due to the condemnation of the player base Riot scrapped the retune entirely, despite viewing Lee Sin as the flag bearer of a game warping subset of champs crowding out nearly all variety among junglers.
Fast forward to two weeks ago. Riot informed the players of a retune for Cassiopeia (http://www.newsoflegends.com/index.php/wip-pbe-cassiopeia-rework-tu-guardian-of-the-sands-khazix-new-akali-splash-art-24895/), which was met with equally negative feedback as the Lee Sin retune. This time Riot's plan was more egregious, as not only did they plan to pull a complete 180 on Cassiopeia's power curve, but also play style by shifting all of the power out of Cassiopeia's poisoning skill shots and dumping it into her single target targeted ability. Cassiopeia players were very open to a retune as she is clearly not a powerful or popular champion (though this is only true regarding Summoner's Rift), unlike Lee Sin players who wanted Riot to put the nerf gun down and step away, but were extremely negative towards the direction Riot was taking her. Unlike Lee Sin, Cassiopeia's rework was pushed through.
What was the difference? There's a boat load of Lee Sin players, but Cassiopeia isn't nearly as popular, and popularity is tied directly to the in-game strength of the champions. This creates a dangerous downward spiral regarding the relationship between Riot and the playerbase. Players are unhappy that their favorite champion isn't strong enough, but not many people play the champion due to his/her weakness, and thus Riot doesn't listen to the concerns of the players who have invested time/money into the champion!
Well, only half of that breakdown is on Riot. We know that we can put the brakes on terrible reworks as its happened before (Lee Sin). We just need to come together to help each other out. When Riot gives details on the Sion rework we need to raise the alarms if it appears that another champion will lose his soul. Sion players won't be able to do it on their own as he's one of the few champions as unpopular as Cass.
EDIT: Guys, don't give flack to people who say they enjoy the Cass retune. The whole point of this thread is giving a voice to the little guy. Refute their points, explain why their reasoning may be wrong, or give your own opinion back to them, but theres no reason to be negative towards them.
