Malphite deserve a hard nerf on his q

{quoted}

Ummm it doesn't do a lot of damage even with comet while also cost a good amount of mana to use.

Like it does about 200 damage at level 6, which is actually about the same as poppy q on a Aatrox at level 6. While also being close to a kled q in damage.

That doesn't take into account the AP scaling of Malphite Q and Comet, or the combined damage. Let's face it, if you get hit by Malphite Q, you're gonna get hit by Comet. Only champs with gap closers/makers have a hope of dodging it due to Q's applied slow. Even then, the trade off will be in Malphite's favor. Mana also really isn't an issue because of Manaflow Band.

In addition, this theoretical damage output doesn't even take into account the lack of access to MR early game. He acquires three advantages (Damage, Poke, and Clear) and turns into a mage with mad tank and sustain capability. You can't outlast him and you can't out damage him.
