Has Malphite been looked at in a while?

Because a full tank champ that slows auto attacks and movement speed for an actual 5 seconds when he's not too busy knocking up your entire team in a hard-to-miss ult is pretty overbearing, especially when using auto attacks and moving is so, so vital for a whole lot of champs these days.

I get that he's a champ that's designed to not care when Ashe's arrows plink against him, but that doesn't mean Ashe shouldn't be allowed to shoot arrows at him at all, and that certainly doesn't mean Ashe shouldn't be allowed to move at more than 2 ms for the next five entire seconds, and that especially doesn't mean the big rock should be allowed to sprint away at lightning speeds for the next five seconds, either.

Even if all these crippling debilitations are considered healthy for some reason, they shouldn't last that long. Especially not in a meta where people usually die in 3 seconds, anyways. If he's allowed to take no damage as he throws a massive-damage slow at one single guy, that single guy is literally doomed if the rest of the team runs away, and absolutely useless if the team goes in to help. It's basically turning a fight into a 4v5 without even killing anybody, with a moderately short cooldown for whenever he feels like crippling anyone else.

Tanks are always a problem when their damage can scale off of defensive stats, and this guy just loves rubbing it in. That, and his base damage is rather massive on most of his abilities. For some reason.

Could you just look at him? A tank that can knock up an entire team shouldn't be allowed to decimate a single champ as well. It's obnoxious in a Singed way, but at least Singed is designed around running away, not towards.
