More transformations = nope. The team already said there won't be SSJ2 because it wouldn't make sense with the storyline (which is written by Akira Toriyama) and it would be an offense to alter it. Also, it would require some character modeling and stuff, which brings me to my second point:
The team also said new haircuts will only be added if someone can model them digitally in 3D and send it to them and I guess it's the same for the Dogis and clothing; and even if that were to happen, I don't know how much they can change the game because it's supposed to be a server revival. They're not just making their own game... which also brings me to a new point:
Creating new classes and races will need, other than more models and skills, a massive rework and changes to the original game. Like I said, it's a server revival so I don't know how much they can change other than class and skill balancing or day and night system. They, not long ago, made a post (click there to check it out
) where they listed all the suggestions we made that they could try to make possible in the game. Check it out so you can see if something you proposed is there. Maybe they can add some stuff to their list.
Everything you said seems pretty cool to me but many of it is just not possible, or at least not anytime soon. I don't like SSJ2 though, the storyline makes it impossible and I personally like SSJ more than SSJ2 or SSJ3.
