I disagree. One Ice climber is *WAY* worse than none, because it sets a precedent for future smash bros to follow. If Ice climbers are cut, then can always be brought back next smash. If it's solo, chances are that next smash bros, it'll be solo again.
Basing things on the entire future of the series when each game takes so many years to develop doesn't seem like the right way to judge things, especially when this game isn't out yet. This is still the next Smash Bros.
That said the idea of Ice Climbers being cut down to one sounds completely stupid. I mean would the A.I. really be that much of a problem? And if it was, just make a new character instead of maming and redesigning Climbers.
