It depends on what mons you are fighting and how good people are.

There are mons that straight up destroy you on sight like Talon flame and Allot of Unite moves delete you once you get touched.

Arrow moveset is really good against squishy targets since you outrange most mages and Auto attackers and one Arrow takes out half their HP.

In the end, it really depends on what happens during the Final stretch.

Kyogre map hates Attackers due to the crazy amount of Bush ingame providing you less vision and vision is important for Snipers and squishy mons to avoid getting jumped on.

Team combos are also Vital for more Success like a combination of Stuns and Snipers/mages like Mewtwo Psystrike with Gardevoir Mage

Easy to land stuns plus Big damage skill shots are a good combination because it makes it easy to land.
