Build

Cube: Resilience or Bastion are the best option, like most units in the game. Quantum could be used if your team is low on burst generation.

OL Gear: Support unit so it doesn’t matter what you get. ATK, max ammunition and elemental damage are desirable but not required.

Pros & Cons

Awooo
Amazing support providing offensive buffs and repairing the cover for the team. Used since day 1 and doesn't look like she's going anywhere 3 years after the release of the game
One of the highest team attack buffs plus max ammo capacity, CDR and crit damage. Overall a complete buffer that can be used on any team composition

Needs 3 rotations to fully take advantage of her buffs and CDR
