How do i know im one-tricking a hero and not maining?

I play kagura like 95% of my games even though i have plenty of other likeable heroes to use like xavier, cecilion,lylia,zhuxin,etc. but i just don't feel the need to use them and just think kagura can do the heavy lifting in most drafts i see. According to what I've seen in this subreddit, this feels more like a one trick than a main. And yes, im good at xavier and the others
