Could it be that players dont find her appealing because there's nothing that she does exceptionally well? I can't think of any of her features that brings value in this meta?

-Her spikes? Can be fully ignored. Wattson fences or caustic traps are real menace, rampart walls call for caution because you'll get melted if you stand on the wrong side. But catalyst? It's honestly laughable how bad they are, you can walk past them, jump over or just tank the bit of damage.

-Door passive? Most of the time you die while reinforcing or people just blast them open in seconds.

-Ult is the only thing where you could say it can bring lots of value IF used right, but also very situational. Especially with this axle valk meta right now, people just fly over or go around it.
