She's the tank who can't tank.
She's the counterer with a 10% proc who will die when hit.
She's the TDH-er who has to sacrifice an awful lot to be either; a very bad tank, or a very bad damager, or a terrible 'hybrid'.

What I mean by all this is, has there been a 5* unit who, compared to the meta at their release, has been more useless than Elfreeda? I'm struggling to think of one since I started playing around April. You really have to clutch at straws to find any use for her (other than her TMR of course). Like, maybe she can be useful with Fryevia? Or, maybe she can have a niche use where you need to break ATK/MAG and provoke on a single unit... Nah, she really is just awful. Which is a shame because I love her sprite and victory animation.

The only contenders I have in mind for "Worst 5* at their release" are Gladiolus (the 'not-quite-as-bad' Elfreeda), Duke (jump meta when?) and good ol' whipping girl; Queen. Are there any more for consideration? A hidden gem? A scuffed rock in that ever-so-lovely Rainbow pool?
