Put a Haste Reservoir right outside the Fortuna gates, this will buff movement to PT and allow the [Wisp] player to teleport back to Fortuna instantly once the fight is over. Just go straight up in Archwing, then press 3 while aiming at the Reservoir to teleport to it. Then hold the door open for your teammates. This will save a few seconds of waiting on door opening per run.
Aura choice is flexible; whatever the squad needs.
[Wisp] is not meant to play solo. Both [Saryn] and [Chroma] do that better, [Wisp] is used to complement them in a squad.
Adaptation Rank doesn't matter much, it stacks up to 90% resist at all ranks, only the % per hit (5-10%) and duration (10-20s) scale with rank.
