i used to farm (ineffectively) rune stones/BEWRs/BEARs/Craft packs in Balok...
over (loooong) time, i had more than enough for my skills and sold the rune stones overpriced
ofc this was when instances are alive. u can still get ppl to join instance raids. now all ppl do is macro xp
also ppl outgrew the instances. most ppl are 105+ and dont get drops here anymore
