CertainlyT gets hell for trying new things.
Literally, he is the most creative designer there is. Sure almost all his champions are overtuned but that is just a reflection of his attitude. He is ambitious and loves to shove a lot of stuff into one kit. Almost all his champions have a very high skill cap, and all of them are unique. This leads to making a very fun main to play. It means that if you get good enough at one of his champions (which takes work) you can play them to high potential. I just feel like you guys (the community) blames so many things on CertainlyT when he doesn't deserve such criticism.
This next paragraph is addressed to CertainlyT himself. Your attitude is shit. You mock players that mock you, you don't reply with kind words or listen to your community. In this I agree with the community, you need to improve your attitude. I mean I know it must be hard with everything that is said about your champion designs but pull it together. I think if you explained your ideas to the community and the potential of them they would have much more sympathy than what they have now.
Thirdly, Morde needs to be started from scratch. The idea was a good one in theory but now after 2 months of being live he still has a win rate of 58.3%. That is too high. He has a banrate of 50%. He is relatively fun to play as but not fun at all to play against. There is little to no skill in his current kit. In my opinion all of your other designs work well for what they were designed for. Morde however does not meet your requirements.
however, he goes so overboard sometimes that I think he only cares about his champion being fun and disregards how that champion affects the players who have to play against them.
is a prime example, I tried him and had fun but when it was time to actually fight one, it was just horrible. So many things just to kill one champion that all the effort that goes into shutting a Yasuo down just doesn't make for a fun experience.
