I like the idea of Future Vegeta becoming SSJ after Future Goku died, but over the years Future Vegeta got a little rusty. Meanwhile the other Z Fighters are still training or at least staying the same within those 3 years. I'd like to have Future Vegeta SSJ = Goku SSJ (Namek).
What about Future Vegeta Base? At least in Toyotaro's Manga, Vegeta doesn't have SSJ, but he's still more powerful than Future Piccolo.
How about this:
Goku SSJ (Namek) = Future Vegeta SSJ (Anime) >>>>> Future Vegeta Base (Manga) >= Future Piccolo >>> Vegeta (Arc Mecha Freezer) >= Piccolo (Arc Mecha Freezer) >= Goku Base (Namek) = Future Vegeta Base (Anime)?
