Should I add this when I apply?

Along with other things I’m interested in playing, League of Legends ( a computer game) is one of my favorite things to do. I’m currently ranked higher than the top 1% of North America, and I was wondering if it would help or destroy my Application to a school with a League of Legends team. Harvard for example has a team. If i apply there, should I add this?

It will not destroy your application to include this ranking.
