Devour wasn't as mig of a problem as you might expect for us, except that we got zig-zag pattern every time for a whole session which trained us wrong, as a joke
I think the main issue with the mech was that if one person got clipped & your tanks weren't on the ball to invuln and step in, it was an instant-wipe. So very, very unforgiving for a first fight in a tier!
