As a pitcher's park guy, I agree with hockey1984. OBP is my most important stat for batters. Power hitters still get theirs, just somewhat less. What the pitcher's park really does is turn a .750 OPS hitter into a .650 - from somewhat useful to a waste of outs. You have to manage around your offensive players like that.
One tact I've taken is that I usually sacrifice a bat at a premium defensive position, like SS and/or CF, and use a hitting Catcher instead, sacrificing pitch calling. I know some will debate this, but my experience is that the park compensates for the presumed increase in ERA that lower pitch calling enables.
It's a lot easier to find a marginal C who can really hit, than a plus defender who can really hit.
I actually had an all-offense team once. Inherited a lineup full of sluggers, put them in Yankee Stadium. It was kinda fun in its own way. I dropped the team when I realized I could never, never acquire "enough" pitching.
