A huge emphasis I've noticed, has been put on swordsmen for this game. With the exception of Meta Knight, the rest all have counter or counter-like moves. Ike, Marth, and Lucina all share the same counter attack. Supposedly as I've read, Cloud will play similar to Shulk (kinda reminds me of Shulk, just the Monodo Sword and beach boy charm are absent) with a final smash like Ike's.
It really reminds me of a debate I once had, regarding Link and Toon Link, and Mario and Dr. Mario. You can make minor differences in how they play, and call them completely different characters, but Smashers aren't stupid Nintendo. So Dr. Mario throws pills and Mario throws fireballs, or Dr. Mario runs a bit slower than Mario, do those facts really warrant completely different spots on the roster? Hardly. The reason some people are so outraged over Cloud's addition is because, I think they were looking for something more original.
Someone modeled differently, and didn't benefit a competitor (Sony). I think they were expecting Issac, King K. Rool, or Wolf. Thus the reason why so many were flabbergasted after the recent Direct presentation. I'm just a bit miffed because Sakarai added the character simply for its popularity in Japan (similar to how Sonic got added in Brawl) without looking at any other demographic. Maybe he did, I don't know, bu given the track record of adding characters whom are popular in the franchises home country.
Shulk also comes to mind (I never really saw anyone go gaga over Xenoblade when it was released for the Wii) and rumor has it Xenoblade was extremely popular in Japan so.....
