The major difference though starlord - MMOs tend to fail pretty quickly if the game isn't "up to par" fairly fast, even if the MMO itself is fine, the new generation of MMO gamers are just, fickle. 2.0 has content but not a lot of it when you get down to it - you blow past almost all of it since it's simple 4 man content till the final 2, then you get a few end-game dungeons you spam and the coil, not exactly a lot of content there (Quests/FATES/LEVEs can't be counted as content since those are basic systems for games to level you.)

By time 1.23 came out almost no one was playing XIV, so by time let's say 2.7 come out, unless this groundwork has given us amazing content that separates this from the rest, SE will be scrambling to try to keep people interested. It's a relaunched MMO so lack of content is to be expected, but at the same time, if according to yoshi "end-game is the start" like other MMOs, there's not that much there yet.
