Is the ballpark tendency enough to sway you from the better players?
Yes and no. In Camden Yards I may choose a player like Adam Lind over Ed E even though Lind is clearly the inferior player. In a park that favors LH hitters I feel like I get a better bang for my buck from Lind. I also look at which parks the other teams in my division are using. If they favor RH over LH I am less inclined to have as much of a LH bias.
I tend to be swayed even more when it comes to pitching. Staying with the Camden Yards example, I'd be much more inclined to take Jose Quintana over a pitcher like Corey Kluber. Kluber is a better pitcher but, like Adam Lind, I feel that Quintana provides more value in this particular park.
That being said- there are certain players that I will use in any ballpark, regardless of their dexterity. Players with high OBP, doubles, and/or strong defense are always my preference. Extreme ballpark ratings are a useful tool in finding value to supplement a core group of stud players.
Thank you for clarifying Jeep's question. After writing this response I have a better understanding of what he was getting at. Instead of sticking with the original strategy of LH power bats I may have been better off changing course and picking up doubles hitters with higher OBP. I guess at the time I was so set on a particular strategy that I lost the forest through trees.
I appreciate both questions that were posed in regards to my post. They helped me rethink some decisions I've made and opened up new solutions that will undoubtedly improve my future roster construction.
