Is Guardian as severely disadvantaged against Libra as it seems?

Fundamentally, Guardian is meant to be a tank and damage sponge for the group. Against Libra, this pretty much doesn’t seem possible. Using Guardian, the sheer amount of AOE spam made it impossible to hang in there and tank. Madness procs were constant and largely unavoidable. I had to give up the role and resort to unlocking my target so that I could run. Guardian’s dodges are simply too immobile to avoid Libra’s sudden AOEs, making sprints and retreats an absolute necessity.

My teammates (Wylder and Duchess) pretty much then panicked, and didn’t know how to approach the boss and attack. We didn’t even get the boss to 50%, because no one was providing reliable offense.

I’ve actually done quite well against Libra with Raider, so I feel like I do have an understanding of the fight itself. It seems like Raider is a much more reliable tank here. Guardian is a secondary character that I typically enjoy a lot, but I do not think he is good within his role vs Libra, and should play more of a support role here.
