There are dozens of other Trusts who are just another variety of "Heeeeeeeeeeeeeeeeeeeeeeeeeere's bad DPS!" with no real utility or difference between them other than MAYBE weaponskill properties.
Cornelia was unique, and she was *useful* to almost any low-man party set up. I've known it's coming, but I'm going to miss her, because there are literally 25 trusts I would give up-- not 1:1, 1:25-- to keep her.
