No shit, you pretentious ass

In a matchup with evenly skilled players, Pantheon has the advantage
One-tricks are able to win in every matchup because they have more experience on their champ.
I one-trick Nami in Solo Q and I beat Blitzcrank all the time, even though Blitzcrank demolishes most Nami players.
Also
Darius will always win an extended trade against pantheon.
Darius wins every extended trade..... Pantheon goes in for short trades. Also it's not uncommon for Pantheon's to max E in a melee matchup. Pantheon should be able to easily out-trade Darius as long as he dodges Q (his passive shield still blocks crippling strike damage)
Dodging 2 auto attacks in a trade is nothing to sneeze at even if it still applies bleed. Pantheon can back away before it's fully stacked anyways.
Darius wins these trades since he has better base stats
This logic doesn't make sense. Doesn't matter if he has better base stats, Darius Q is relatively easy to dodge (worst case scenario, Pantheon W's to Darius for the reduced Q damage), meanwhile Pantheon has a point and click spell that does absurd damage early game. Also Pantheon takes Thunderlords for very effective early game poke (E hits 3 times for easy proc)
decimate has a healing mechanic
Good Pantheons take ignite. If they don't have ignite then they are playing Pantheon wrong.
Whenever pantheon goes in to throw his spear, Darius can simply step forward and trade with decimate
I wonder what horrible Pantheon players you go against, Darius' Q is so easily telegraphed and easy to dodge if you anticipate it. Once you dodge it you literally can't lose a trade against Darius as Pantheon.
Pantheon is still the king of first blood.
If you want me to use another example or if you don't want to rely on early game to beat Darius: Once Gnar completes Frozen Mallet it's almost impossible to lose in a 1v1 to Darius because you can kite him infinitely (unless the Gnar is terrible)
