The last year ive spent practicing Bowser has been pointless

When I first started playing melee a year ago I started with kirby for a week or two, and then swapped to bowser and have mained him the entire time since. I would play kirby on rare occasions, usually just vs my friends who were new to the game.

Lately I've been feeling unhappy with bowser, and trying out other characters. I have an alt I use to try different characters on, and whenever I play kirby on that account I absolutely destroy people at the fairly low mmr its at. So I decided to try him on my main account, and consistently I perform better with kirby than bowser.

I can fight the same opponent with kirby, and then with bowser, and I'll almost always do better on kirby. It feels frustrating that the hundreds of hours I've put into bowser mean basically nothing, since my kirby with less than 10 hours is better.

TL;DR kirby is an easy character to suck people with.
