Overall, defense does help, but HP help more, and doubling defense for a large reduction in damage output is not worth it.

The break even point is heavily weighted towards attack value so that even a modest drop in attack cannot be compensated for by a huge increase in defense (even +10K or +20K defense). However a drop in attack can sometimes be compensated for by a comparable increase in HP.

You just have to do the math after gathering some data. You don't have to gather a lot of data either. Just video tape one battle with a boss where your bots survive 6 or more rounds. that should be enough. Vary the bots so that they have a variety of Defense values, then you can figure out the tradeoff for that particular boss and see if a particular decrease in Attack is compensated for by the combined increase in HP and Defense.
