Willo doesn't have the amount of air potential you think she does. Deep Roots will get her killed 80% of the time if she's in the open.

In a 1v1 situation Pip will definitely fail without the proper damage to counter Talus. Use his Weightless buff (as of OB62) to use mobility against Talus, and finish him off before he has time to lock onto you again.

If Vivian uses her shield, aim for her feet if you’re running direct damage, or the ground below her if you have AoE. This is extremely useful in any range combat with her.

If you have the Focusing Lens legendary, Skye can be countered if you use a Front Line as your meat shield. That Skye has nowhere to teleport; landing all five shots on her will be more devastating than you think.
