Just like Agility Zacian(which is never used), Agility Dodrio is never used. I know it's used with Tri Attack, but if no one uses Tri attack, no one uses Agility, which is dumb. It looks like all Dodrio in Unite are used with same emblems, held items, battle items, and movesets. The only thing that is different is if you use your central or the opponents central. I'm just asking why everyone uses Drill peck instead of Tri attack.
I asked this question on the Pokemon Unite subreddit, and it seems that the Tri Attack build provides less damage and utility as a whole.
Jump kick has a shorter CD, has some short CC, can go over walls with no boosted attack, and because of all of that is somewhat better for recovering from an opposing stun or slow effect. Plus it deals damage
Tri Attack doesn't let you deal the most overall damage (on account of it only being multi-hit at its weakest), which can be a con against a moderately large group since there's too much HP to work on.
Why isn't Tri Attack/Agility Dodrio used more often? (Reddit)
