So the new Xenoverse 2 DLC has what I wanted all along. To acknowledge SSJ4 as superior mess around with the timelines yourself.
Yeah, SS4 > SSB all day. I might not like the Magenta fur, but mixing in the ape form was a sick idea.
My main problem with newer transformations is that they have very little build up to them, they just kind of happen. And then, said forms can't feel badass when (Ultimate)Gohan and 17 can keep up with them when they train up, or Frieza going gold in 4 months. While I have a couple gripes with SS4, it did at least have not only build-up, but was managed to look tough in a fight like SS1, SS2 and SS3. That said, if I remember, it was only called SS4 for the sake of simplicity. Which makes sense since it requires more than just getting stronger. And it gave a good reason as to why only a few people could learn it(Goku and Vegeta being born with tails, and Gohan, being the only half Saiyan to get it in a couple games because he's the only half Saiyan to have a tail too.)
UI had been alluded to since Whis began training Goku and Vegeta. And the form itself has had some buildup. Though it'll probably annoy me that more people won't eventually learn it in the same vein as Kaioken, if we get more DB shows. But in every fight we've seen it in, it does look impressive. While I do like the Silver hair, I think I still like the black hair version more, simplicity makes it work.
