Is Psychic really that bad of an attacking type? And if it is, should Latios and Metagross avoid using damaging Psychic moves?
Psychic is good for certain types of pokemon, but mostly I don't see it used on Latios / Metagross. The pokemon who mostly use this move would be Reuniclus / Espeon / Alakazam, because of their ridiculous SpA and STAB that they get from it. Latios and Metagross CAN use Psychic, but Latios would rather hit with Psychoshock, and I haven't seen many Metagross's with Psychic.
