I feel like transforming is kinda pointless and is just for design in this game and i kinda feel like if i´m using jiren and fighting a saibamen we shouldn't be doing the same amount of damage

Once again, stats matters.
Take Jiren against a saibaman.
Then simple punch both one after another, you'll see the difference.
This game isn't a RPG. Killing one enemy with a single punch is anything but fun in a VS game. Take a look at Whis to see how it is cheated.

You can try that also with speed. Move both from border left to border right at the same time.

And again for ki blasts.

Stats matters. End of story.

O ok
