Keep in mind, even as a Veteran of FFXI, I do not make this correlation. My preferences in video gaming stand from a library of games that stems beyond FFXI or even the moniker of MMOs. In fact, my example was made specifically using real-life hobby correlations to distinct such. In my opinion, FFXIV stands strongly on its own now as a flagship title within the seriese and can bear the brunt of recommendations derived from other titles without worry of detracting from its own existence.
Two cases in point, we have received both Golden Saucer, and Triple Triad, yet neither of these take away from the identity of FFXIV. Mechanics and ideas from other titles, including FFXI should not be scorned simply on the bases that it is not a FFXIV unique mechanic, but rather the mechanic itself should be weighed and measured on its own merits.
What about the FFXI mechanic is bad? (Rather than assuming it's bad just because it's being referenced from FFXIV)
