This build is for the index, and never dying. Turns out shield gating is really good and your shields don't matter if you can just get them all back before gate expires.

As soon as you get hit your aegis will proc regening your shields instantly, with all the boosted shield recharge you will get your shields back before the invulnerability wears off. You can use her shield pillage offensively with this, it will send out a quick pulse and steal shields/armour.

Unlike other tank frames, this will last for infinite levels and with reduced stats from financial stress. It's the same at 99 stress and level 9999 enemies as it is at level 30.

[Enemy Radar] is just nice for index but can easily be replaced with CP.
