Hi,

it appears that Crustle hasn't got its Attack Base Stat updated to the GenVI mechanics.

Its attack should have raised from 95 to 105, but it's still 95 in Pixelmon.
Here's the proof:

I don't know if there may be other pokemons which still need their base stats to be updated.

If more informations are needed, feel free to contact me,

Thanks,

While you are looking at an ORAS set, you are still clearly using the SM damage calculator, as evidenced by Aurora Veil's existence on the page.
