Considering they are actively balancing and no unit is meant to be 'OP' without serious drawback then probably.

Been playing faye faye in the beta to see if she can be h2h viable and guards do seem a bit slower at lawnmowering infantry than I remember, they still end up with 400+ infantry kills tho so they seem reasonably balanced? The only absolutely bonkers nonmonster unit I'm aware of that got neutered to a fraction of it's former strength was horned ones, but that was like 3 updates ago.
