I mean if anything it's frankly a weakness.

It's supposed to be.

No, it's not supposed to be a weakness, if anything it's more like a strength. What it is actually saying is that moves - in general - can't be SPECIFICALLY good against something, but rather, they would all have an equal footing if at the same power.

example scenario - Bulbasaur uses razor leaf against Squirtle, although the background canon says that it's more effective against water, it's not in the case of the Omniverse. You and your writing partner can chose to write it as being more effective, but that is purely fluff and fodder. If Squirtle also hits Bulbasaur with a water gun at the same power that Bulbasaur hit Squirtle with his Razor leaf, then both moves would do the same amount of damage. Neither of them being more or less effective (outside of rp fodder/ fluff).

The same goes for defensive moves, they can't be more or less effective against a certain type of move/ power/ Character.
