I say I have my issues with the design with the caveat that I still enjoy it and mercy in general currently.
I think some of the things that make Valk good, are ironically the same reasons (or at least, play into the larger role) why a lot of people dislike it as a whole.
This often seems to get muddied somehow and people claim it’s weak when it’s really not.
Here, I’ll link a thread where I go into some depth about my personal qualms with Valk.
