Unlike some people, I never had this seething hatred for clones. If anything, I embrace them. People tend to have this unrealistic expectation of clones stealing slots, when they take substantially less work. I swear a large part of this vendetta against clones that some people used to have came from that sort of view. In smash 4 for instance, the alternative to having Lucina and Dark pit was not getting your most wanted dream pick in the game: it was not getting Lucina and dark pit. I feel as well that the larger the roster gets and the game gets, the less controversial clones become. The lingering hatred for clones emerged in a post melee environment, when 6/13 newcomers were clones in some way shape or form. Nowadays, when you have such a large, diverse roster, a few last minute clones on top is not the end of the world. It also helps that with Ultimate bringing in so many people, clones don’t have that same stigma they had in the old days.
If a clone is done right, like a Melee Falco or an Ultimate Lucina, Chrom, or Ken, they are awesome additions. I love seeing the subtle differences that make the kit mesh differently. If anything, I wish they would go further with the echo concept in the future. Obviously I want more Chroms and less Daisys if that makes sense, but honestly simple small tweaks, even if it is just sharing a move with a different fighter like with Chrom, goes a long way. I’d love to see a Shadow echo fighter with a Mewtwo Up B for instance.
