I would like to provide a counter opinion about tactition being too hard. I would like a higher level of difficulty than tactition. It is fun for a first play through where you are not familiar with the skills and builds but once familiar, I would love a real challenge. Our team has just bulldozed tactition just by chosing whatever skills and builds suited our fancy at the moment. Many Leeroy Jenkins moments later and we pretty much got to the point of being unstoppable.
