I somehow agree with that. My imagination isn't as big as yours, but I'm really disappointed with SCV mode: while there are good things, other options really suck (malfested voice doesn't sound malfested at all, just autotuned). I really wish the creation mode was deeper: you could choose the face outline, a different nose, a different mouth, different eyes... To create unique characters who don't look the same.
And I totally agree with the exclusive fighting styles, I reallt loved it in SCIII, my characters felt so unique! Yet as most people say, it would be a nightmare to balance, especially on the competitive scene.
And I'm totally in favour of the come back of the great single player modes!
Yet on my wishlist now: just a SC game. A real (and good) one... Pwease :(
Characters: What do you mean by Edgemaster becomes Necrid-like?
That I can answer (I guess) :D A mimic would copy various styles at the same time, not change weapon and styles between rounds. For example (as it is easier to imagine), EM would use a staff and use various moves from Kilik, Mi-na, Siegfried, Nightmare, and Hilde, all mixed!
And that's a mimic I would like to see: to me, EM, Kilik, and Elysium are useless, just filling spots while they are simply a playable random button.
