Nice tiers, BGIII! And glad to see you checking these builds out, as the reigning Bat-Expert (I was gonna say Batspert, but that sounds dirty) around these parts- I had to use your own thread for inspiration and helpful notes while statting up my own. I actually came up with my own "Tiers" list when I was finished statting up the Bat-Family, to see if I'd got it right (thankfully it turned out pretty accurate to what I think the tiers are in the comics). I'll post it up when I'm finished with the whole crew (there's Huntress II and Batgirls I through V left). Actually, that reminds me I should probably stat up Batwoman. I mean, she didn't join the League or nothing, but she's one of the gang, sort of.
My own builds of most of these characters more or less stick to what they ended up with in terms of powers & traits. A few guys are era-specific (my eighteen Superman builds, for example), but the rest are meant to kind of fit their Post-2000, experienced selves. With a few notes here and there if things changed. The multiple Crises and Continuities makes too much accuracy impossible (never mind all the guys with "Super-Strength" being a listed power, without any hint as to the level), but I make a go for the heroes at least being relative to each other.
