Are you seriously making a judgement based on online spam?
As for Natsu, I don't care if she comes back or not since she comes back or not since she shares the same personality traits as Naruto. The most important things to me are the gameplay and balance. It doesn't matter who they bring back if the gameplay sucks or if Taki sucks 6 dicks like she did in SC4 balance wise. People will just continue to ignore her.
Every game since SC2 has been divisive because of gameplay changes, so SCV is no different. SCV was designed around newer players who haven't played SC in a long time by shortening movesets and nerfing backdash, and the Street Fighter crowd with 2D mechanics and Viola/ZWEI, so it's going to be interesting to see which direction they take this next game, which I'm worried about because of how long it's been to make an announcement.
I know everyone is hoping for their "baby" to come back. I just want a fun game to play. If the gameplay and balance are great, then everything else will work itself out. Otherwise people will be asking for SC7.
