what stage, though? it seems like it was nerfed slightly. i was able to kill samus near the edge (where the AI starts in training) at 100% in the old version, but it took around 110% in the patch, which just barely kills. so yes, it's about 10% weaker in terms of knockback now, but it's still fairly strong. nice!
just tested this. fox's up smash kos mario in the old version at around 105, where in the new version, it's around 110. i guess it's 5% weaker knockback now? seems like both AIs are using DI.
