Is this legitimate?

So we had a Mordekaiser today we played against... I was playing fulltank while he ran around oneshotting everyone with a single autohit for the entire game.. i knew mordekaiser was strong, but 3k damage in one dose of damage, is that legitimate? (Had to take that kind of screenshot because i wasnt fast enough with the programm lol)
