How many people actually main Meta Knight here? I find it silly you let other peoples choices to main a certain character bother you. Everyone here could be maining Dedede and I wouldn't care one bit. I'd still be maining him.
If you like something then stick with it. Don't let the mains of others discourage you from playing the character you enjoy the most.
If Dedede or Kirby ended up being the gods of the game and everyone everywhere used them. I wouldn't change what I do ever. You shouldn't let it bother you that others use the same characters. Thousands of people play this game and theres only 35 character choices. Chances are, thousands of people are going to share your main no matter what it is.
