That's the point there are even stronger forces out there and now the only way to continue, is to create new powerups out of toriyama's ass. It's like he climbed so far up the power scaling totem poll it's impossible to have good writing going forward. What purpose does SSJ levels 1-3 serve now if we have God form ? You can't be a villian worth episodes in a series unless you are threat and danger, and that's only possible if you are stronger than the strongest form. It's like Toriyama didn't realize the corner he was placing himself in when he started relying on powerups for everything.
Yeah, this is the main reason why I'm not feeling any new dbz. I mean once upon a time ssj2 was wow status...and then became completely useless by the next saga
After a while you just get exhausted by the constant power-ups and powerful villains.
