Malphite is not really OP, but his Ult is incredibly strong in Teamfights. He is really good against AD team comps, so right now where AD itemization is the best so everyone is picking AD champs, he is a strong pick. He is stronger now than he use to be, but he was always strong thanks to his tankiness and his ult. However this season in particular is special because a lot of teams are primarily AD and most of his counters are not in a great place.
If you want to pick against him or just know some champions that currently are pretty strong against him in lane, here are a some of the champs I consistently have trouble against.
- Tanky with lots of Damage, not much you can do to her but plenty she can do to you.
- This is actually my go to pick against Malphite, he is strong and you can't hurt him.
- Just a really strong early game bully, he can poke you, out sustain you, and ignores your Armor plus free Armor Pen with is E.
- He deals Magic Damage so you can't make use of your Armor benefits, plus his troll pole can dodge your ult.
- The barrels are so annoying...
- Gragas is tanky, deals a lot of damage, and has just as much CC as Malphite, however the main reason he wins in my opinion is because he can out sustain Malph.
- Mao deals Magic Damage, is tanky, has %Hp damage, and can willingly take significantly less damage.
- Tankier with more CC, better at 1v1 dueling than Malph is.
- Broken amounts of damage for only building tank, plus his damage is Magic Damage.
- His ult makes him auto-win fights and he can dive you easily.
- Obviously because he out sustains and deals Magic Damage.
-- Wukong can reduce your Armor and can harass Malphite before he gets too tanky, I have been on both sides of this fight and never expect Wu to win yet he almost always does...
- This is an odd one but Yasuo's damage early game is ridiculous and his Flow can block a significant amount of Malph's damage. His ult gives him bonus armor pen and he is highly mobile.
