I don't really have a personal opinion on the new weapons, but I think it's good for FFXIV.

One of my friend asked me to show him FFXIV last week. I showed him all the classes, one after another, with various pieces of gear (mostly DH and NM gear), and it's first comment was: "The gear looks really dull and unimpressive for someone who has multiple 50's and cleared all content ...".

I think that these types of weapons will appeal to new players, and motivate them to get to 50.
