Whats your highest crit in a real match on summoners rift normal

I got to 2.3k on Gangplank a couple of times

I think it was Season 4, (<Old pink one) and I dont remember what else I had, but I also had a megastacked Q and you could crit with the Strike and I one shot a nidalee with a 2.9k hit. It was amazing

It wasn't a crit, but back in Season 4 I was playing Thresh in a normals match that dragged on past an hour, resulting in my final build being .

Their twisted fate walked up to me and pulled out a gold card and (whip sound effect) one shot him for about 2k.
