FURIOUS ABOUT MY POKEMONS MOVESET!!!!!!!!!!!!!!!!!!

I GOT MY FIRST GYRADOS, AFTER MONTHS OF WALKING!!!!!!!!!!!!!!!! AND I GOT BITE AND CRUNCH!!!!!!!!!! CRUNCH!!!! Crunch is worthless for a gyarados!!!!! It does NOT counter electric or rock types, so it is worthless! Why not replace crunch with earthquake? THEN it would counter electric AND rock types, thus making it harder to beat in gyms! The caps was because I am ?. If this doesnt get changed ASAP, I will lower my rating even more. Please fix.
