If butchering his kit and stats and putting it in fixed contestable zones is what you want for Malphite, then so be it.
I also think that Malphite deserves changes, put using Skarner as an example of this is counterproductive. If anything, you could have bringed up that
and
have received reworks despite being insanely popular and having fully functional kits.
PD: you also can learn to play Malphite. You are supposed to save your mana and only spam Q once you have a couple of points on it, not at level 1 (unless you want to stack Manaflow Band or slow the enemy to escape/help on a gank).
