Personally, I think the whole Lucas/Ness thing is a perfect example of why clones should be left in. So what if two characters play nearly identically? Each person has their own reasons for playing the characters they choose, and it isn't always because they think the character has awesome moves. Most of us like Ness. Hell, I liked Pichu for goodness' sakes (yeah, he sucked, and I knew that but I still found his odd attack style and quirky movements fun enough to play. He wasn't nearly my favorite, and I think they made a stupid decision in giving self-damaging attacks to the lightest character in the game, but I would have rather seen him reworked than axed. Pichu with his tiny Beam Sword held in his mouth...). What's wrong with duplicating a moveset if it means that fans get to keep working with characters they know and love?
