Can Riot Stop Enabling Off-Meta Builds that Aren't OP but are Anti-Fun?

My primary example of this is AP Malphite. Yes he's squishy, yes he falls off, yes he sucks in competitive play, but when you're in a norm just trying to have a good time, getting repeatedly one-shotted by an AP malphite flying out of the fog is the opposite of what you want. In lane, if your flash is down (which it will be because its on a 3 min cd and malphite ult is not), he can all in you anytime he wants, unless you want to miss all of your farm and exp. That or he can just wait for his jg to swing by and jump you then. Then throughout the game, you'll just be walking along and he'll come flying out a bush and you're dead. Malphite was designed to be a tank, if you ask me, there's no reason for him to have any significant AP scaling. When he builds tank like he's meant to, he still does enough damage, you could probably take away almost all his AP scaling and it wouldn't make a difference. Enabling off-meta builds that aren't anti-fun is fine, but whats the point of playing a game if its not fun.
