This is a QQ post... I have not had 1 rare since January 1st. I understand it is rare, I know what rare means, but really? I do some archaeology just about every day for a couple hours. This hurts. LOL
People have done hundreads of solves without a rare.. If it's boring you too much, don't do it. The PvP weapon is better and would require less frustration
So I assume you're digging Eastern Kingdoms, which means you are basically looking at troll, fossil and dwarf. You probably have all the rares solved except the sword from the troll and the staff from dwarf, which are both 1/100 if I'm correct. At a couple of hours a day, this just doesn't seem like your luck is all that bad as of yet.
