Malzahar is the Rube Goldberg machine of champions
A champion who has complex gameplay, but has low mechanical intensity is a fucking terrible design philosophy. (http://boards.na.leagueoflegends.com/en/c/gameplay-balance/Ag06yxmK-after-a-hand-full-of-games-on-malzahar)
He's the fucking rube goldberg of champions. And you know what's the worst part of rube goldberg machines? Inconsistency!
When did "easy to play hard to master" stop existing as a philosophy? All the player now has to do is knock over the first domino and hope that YOU RIOT built the machine well enough, to work. There is no player agency in his success, only that of the enemy knowing how to deal with him.
Due to the high skill floor and low skill cap (due to lack of player agency), the kit will only ever exist in one of two states. OP or useless. Because it's all done behind the scenes. Either you will nerf it and player skill will be able to do virtually nothing to compensate for the lack of champion power, or it will be powerful enough that literally anyone can play it and have it work.
