For Bio, the health drain is really nice. Think of her as an extremely good Firefly. Honestly, if you play your cards right, you could even solo the biggest of characters with an underleveled Bio as long as her SA1 is upgraded fully. She has the best offensive capability.
DoW has the best defensive capability out of the golds and does a good amount of damage with 100% extra damage. Definitely, drop her into a team when you get the chance as AI might be able to use it moderately well. In the player's hands, she is extremely good.
Welcome to the game buddy. You can get Slient Kill by doing her prize fight when she comes up. Surgeon General you can take a shot at her relics to see if you get her. I would definitely start lving Cold Stones and Resonant Evil if I were you.
Did only 22 pulls and got Fiber, Rainbow, Temple, and 2 doublicous with the rest being a mixture of Nunsense and Sundae School. I would say it was a pretty successful pull.
