Yes, but no. She's solid without it, but that's all she is. Just a stable, suicide friendly damage dealer with easy armor breaks and non-contact attack blocking. Good for r3/r4 if you're in the early content.
Her real usefulness comes from sig 101 and 182 where she becomes immune to DoT @ 4 and 3 buffs, respectively.
She doesn’t need it at all, but once she is like sig180, after reaching 1 bar of power and landing one crit you will be DoT debuff immune, autoblock immune, and one more thing I can’t remember (nullify immune?).
She goes from a solid 7.5/10 unduped straight to a 10/10 with high sig

highest sig possible is also great
