Shit I'd cut out:
- Black Star DB saga entirely. Just don't even attempt that worthless throwback to early DB if it can't be done correctly.
- Super 17 saga, either entirely or just skip to the point where Super 17 actually fights and montage the rest.
- Montage all the Evil Dragon fights aside from San, Si, and Yi. They're the only relevant dragons anyway.
I think it's fine beyond that.
