all heroes and formations are tested and confirmed. And all WM's atk, except her ulti, are physical. The reason she is in the list because of her rapid arrow skill. I guess you didnt even try and care to check but just threw your assumption out.Thanks for the picture but some of the info is not helpful so I don't think I'll add to the first post.
For example, WM against phoenix is a bad idea, that boss is magic immune so most of WMs attack don't work,letting the boss US with a higher HP, likely killing more of your units than it should.
