Blind-Fight is a pretty underrated feat, but if one of my martials has a spare feat slot, I definitely like picking it up (especially as it has no prereqs).
I used to overlook the feat because of its name. It felt like it's meant for fighting in total darkness, and how often does that come up? But really, it combats all concealment, invisibility, and being blinded yourself.
Rolling twice on miss percentile because of concealment is great against staple spells such as blur, displacement, invisibility, and mirror image.
Mirror Images doesn't grant concealment? True. But instead of going with 1/7, 1/6, 1/5 odds to hit on your attack routine, you could just close your eyes and treat them as having total concealment, ignoring their images entirely, for 3/4, 3/4, 3/4 odds. It won't wear down images, but you might be able to put down that slippery mage/ninja without even needing to worry about the images at all.
