Am I the only one who thinks GP is op?

His kit is just so fucking good, Insane DPS from barrels as well as wave clear, his ult also gives him r%%%%%ed pressure all over the map, Oh bot lanes fighting I hit R down there and now my team just won the fight because my ult does great damage and its instant. He can just hold a fight until he gets late game and 1 shots your team with a barrel
