As usual, the amount of people whining about a game they never played is ridiculous here.

Eureka is a reference to FFXI content the way the Crystal Tower raid series is a reference to III content. They have no mechanical similarities beyond the Level Down thing, and otherwise is just another XIV thing themed on an FF game. Also every other relic weapon quest series has been utter garbage so why does anyone care if this one is only slightly better?

Blue Mage in XIV has nothing to do with Blue Mage in XI other than its three-letter abbreviation. The AF is from V, the origin is...original, and the abilities are from classic games in the series like V and not the same as they worked in XI.

And 1.0 was designed to be exactly the opposite of XI in a bunch of ways. XI was a job system game like III, V, or Tactics. XIV 1.0 was designed to use the "other" formula of being able to mix and match abilities not tied to jobs, like VII or VIII. They went out of their way to try and replace tried-and-true MMO systems that were in use in XI like the Auction House with the weird retainer market thing, or making crafters and gatherers equal with combat roles instead of side content.
