@CertainlyT You make EXTREMELY CREATIVE concepts for Champions! :D
Seriously. I'm sorry for all the hate you get. Yasuo having to ult off knockups is a really cool idea. Kalista being based around kiting and dashes is really awesome! Zyra's plants are also very interesting, and the way her abilities interact is extremely creative.
Your creativity in champion design is probably some of the best I've seen out of all the champions.
But. And there is a but.
You create champions for the player that is playing them more than the people playing against them. You seem to create champions that are very fun to play and give the player that is playing them a pretty awesome fantasy, whether it's a wind samurai dashing around and cutting down his enemies and blocking projectiles with a wind wall, or an undead warrior that seeks vengeance and is as elusive as the ghost that she is. However, I think that you need to also focus on how it is to play against that champion. Maybe consult with your coworkers, I don't know.
For example, the new Mordekaiser. Taking control of Dragon is really cool! You even named it Dragonforce, yet another rock and metal reference in his kit. It's such an awesome idea. You let him gain extra EXP in lane too. But think about what it's like to play against him. He either destroys your face, or he doesn't come close. He either takes every dragon and shoves all your towers down, or he sits around getting poked.
You're a great designer CertainlyT. Your creativity is perhaps second to none. I just think that maybe you need to consider that you possibly aren't the best when it comes to actually balancing a champion's kit. I think you should consult others for help with this. This way, we can keep getting your awesome champion designs, but they won't be as difficult to deal with.
Thanks for you time, and have a great day!
