DA versus the Page Rank

[Prrmod]

Folks , how important is the Domain Authority of a website? Recently , i've seen many directories dropping the page rank factor and considering the DA of a website to rank websites? Has Page Rank lost its importance?

Google pagerank means number of nofollow and dofollow back-links whereas domain authority is calculated on the basis of linking root domains, MozRank, MozTrust etc.
