The only reason the clones were even there in the first place was because they wanted to beef up the roster in a really short time, so they take a character, change his physics a bit, and bam! A new character. Hwever, this isn't entirely bad as some players actually like these new physics and would be a bit upsset if those character were taken out. Now me, I only approve of characters being removed if the physics are being changed, which I'm pretty sure was confirmed by Sakurai himself. But on the other hand, If the physics do go unaltered, then no one should be taken out as that would be alienating some players. Some of the clones weren't even intended to be clones in the first place, such is the case with Falco and Ganondorf, so if the physics are changed, maybe the movesets for these characters can be changed entirely to suit the way these characters were originally intended to be portrayed. That's my few cents.
