The paladins melee damage is insane but I feel like once paladin goes into melee there's no coming out. It also can tank quite a bit by blocking fire from an entire direction so it feels to me that it's the unit that leads the charge with predators backing it from behind. My last game I was able to take on a Gorkanaut under tower and smash the Ork Super Heavy to pieces.
However it's slow movement makes it really difficult to reach anything except enemy Super Heavy units. Just want to know how other people use in combat?
