Honestly as it stands in this ultimate, preventing death is far superior to the rez. And I believe you're underestimating the value of troubadour and other ranged damage reduction abilities in comparison to addle. There are many times the damage source is untargetable in this expansion, even some of the boss's casts deal damage from an outside source that targeted mitigation will not affect. Then there's other party qol aspects bard brings, like the cleanse and minne. Idk if you want to look at a broad spectrum of fights or focus on this current ultimate, but in this current ultimate the ranged mitigation is amazing, and the bard being able to self cleanse gives healers a little more breathing room. Ranged are a bit far behind in damage, but their tools add great value. Maybe not enough on a lot of fights, but there are a few where it almost feels needed.
