To be honest, I have a bad feeling more than a good feeling when it comes to new/rework champions
Since you most likely saw the new champion Yuumi (that name reminds me of a cartoon series named Code Lyoko...good days), at 1st my heart melted because i love cats a lot but when time passed i got concerned and began to ask: 1- "is that champion gonna be overloaded with so much stuff?" 2- "is that champion gonna be a balance nightmare?" and above all else 3- "who the hell designed that champion this time?" (since there is an apparent leak of the abilities, doesn't seem overloaded, so ct is most likely out of the question, which will of course reduce the chances of the new champion to become a failure/balance nightmare. So who designed that new champ?)
Anyway, as far as new/rework champion goes for the past few years, I'm actually getting less and less excited. Let's say i'm now 20% excited and 40% concerned and 40% pissed off. Why pissed off? Because champs these days are becoming a middle finger to fairness and a main cause of frustration which eventually leads to toxicity.
You may be saying "well DalekZec, you have to wait and see! You can't possibly know before the release!" Well yeah you're right. But how many new/reworked champion came out and were a disaster for a long period of time to this day? A repeated pattern of this sequence makes it very easy to predict riot when they decide to release a new/rework champion.
So a simple thing to keep in mind Riot Games and to tell your designers. Don't. Fuck. This. Up.
