All right so here's the deal, in 4.1 blues said that if you have all the rares from a particular Race, then sites for those races will have a "much smaller" chance of occuring. I have yet to find this to be the case, as I finally got my last Rare for Night Elves, and on 2 occasions now I've had my map full of all 4 NE sites. Similarly, after some switching to EK sites, my sites recently turned into 3/4 Troll, and I have Dwarf and Fossil (and Nerubian, almost forgot) rares still to get.
Now, I know there are a lot of possible NE sites in Kalimdor, but I thought the coding change was supposed to fix this. I was looking forward to finishing grinding my Tol'vir once I got either Fossil or NE finished, but it just doesn't seem so far that I'm getting any fewer NE sites. I guess I was misunderstanding how the "much smaller" chance is actually functioning, since there are plenty of Tol'vir, Fossil, and even 1 or 2 Dwarf sites in Kalimdor. I would have thought now I'd see maybe 1 NE site for every 5 site clears, but it's pretty much every other one still. Does anyone know if this is just really, really bad RNG that I'm getting despite the "fix", or if it's not working as intended?
