KJD, I disagree, particularly when you look at some of the other Q & A's in the the aforementioned dev chat that specifically asked about the power change that Mark conveniently ignored in his arguments:
Q: so about the end of the "steroid era." does this mean that Home Runs will go down across the board, or leaning towards players with more power? (wetherjenius - Pro - 3:01 PM)A: The change will affect the truly elite power hitters in HBD.
The variance will have a much less significant impact on those player's that do not fit that category. Q: Why was there a need to reduce the number of HRs? How large a factor will extreme hitter parks play into the "Max" HR figures (dherz_263 - Hall of Famer - 3:18 PM)A: 90+ HRs in a season wasn't realistic, that was the major reason. Elite power guys playing in extreme hitters parks will be the guys that I alluded to earlier in the chat.
They will be the player's who have the most variance in the max number of HRs they hit. In other words, instead of hitting 50 in a non-extreme hitters park they might hit 60-65 in an extreme hitter's park.
Q: I have not seen an abundance of HRs hit by players in my leagues, will all HR totals across the board be coming down? (dherz_263 - Hall of Famer - 3:49 PM)
A: Yes, the change affects all worlds and all players
Q: Does the end of the steroid era merely shift stats down, or do you forsee sluggers being reduced in overall value? (mainou - All*Star - 4:45 PM)
A: They shouldn't have reduced value, they will still hit more HRs than other player's just not with the same frequency as before. So, I guess it's just a stats shift coming back to normalcy.
Q: Can we expect HR Hiutters Batting Average to drop off 10-20% with the drop in HR's. If not, approximately what percentage drop will there be? How will it effect OBP? (7Yankees7 - Hall of Famer - 4:46 PM)
A: The other stats won't see a significant increase or decrease. The only change is that they won't hit as many HRs.
Q: Does the end of the steroid era mean that balls that used to be HRs will now be outs? Or will they be other hits? Mainly doubles and triples based on speed? (bjb2378 - Hall of Famer - 12:07 PM)
A: The reduction in home runs will be appropriately broken down into triples, doubles and singles.
