Park Factors jumps all over the place, year over year, when it comes to Target Field. But so did the Metrodome in the later years, so I think it's a fair argument that Park Factors is swayed heavily by the offensive prowess of the home team. However, for TF, Park Factors tends to swing much further to the hitter's side than it ever does to the pitcher's side. I would call TF a hitter's park for that reason alone. In year's where TF is rated a pitcher's park, it's still rated very close to the median.
