Malphite.

He's far from broken, probably one of the weaker champions, but his kit has 1 overloaded ability.

I didn't notice this until I watched a random "troll" video. In the past you could go full AD Malphite and just nuke people with R W.

I then noticed, When you max W first, not only are you getting a shit load of armor, YOU CAN GET FUCKING 120+ BONUS AD ON A 13S COOLDOWN, IT LASTS FOR 10 SECONDS. REALLY RIOT? Obviously this isn't overly broken but against melee champions Malphite is 100x more oppressive to fight.

I personally have beaten Pantheon, Gnar, Jayce, and other oppressive/ranged top laners with W max, it makes you so tanky and you deal like 200 damage per autoattack, not to mention it deals 100ish AD surrounding the area. It's literally a Tiamat + AD buff on a 3s cooldown late game. Maxing E after this just makes you deal sooo much burst damage while being incredibly tanky.

This and the fact tanks like Cho'gath having true damage nukes is probably why the Tank Meta was a thing. Most tanks have a Damage ability while being tanky.
