There is no reason why Zed should be nerfed while Rammus shouldn't
First of all, this is not meant to say that Zed is balanced: he is definitely too strong currently. I'm not a Zed main either (I main his wet dream, immobile mages) so don't accuse me of being biased towards him.
Currently people are complaining that Rammus/Malphite/whatever shouldn't be nerfed as they don't have a high win rate because they are too strong, but because they just fit the marksman heavy, low AP meta very well. One could argue that's true and that they don't deserve to be nerfed just for being in the meta.
However, exactly the same case can be made for Zed. What does Zed love? A meta full of squishies, preferably AD, as there are no AD armor items (except for Ezreal, which is one of the reasons why he does well in an AD meta) and most marksmen don't have hard CC to lock him down (most mages are able to CC him once he ults), and finally a lack of semi-tanky bruisers (Fiora is an exception) as he hates those. What does the current meta feature? Exactly. But still everyone is complaining about Zed being OP and having to be nerfed.
So why should one champion be nerfed because he loves the current meta, while the other shouldn't? Unless you want to tell me that Boards users aren't all 100% rational people, which is obviously not true, right?
