Graphics look polished, with an interesting class system, but what high-level and end game content is there at launch? The release isn't far off and it appears that jobs haven't even been tested yet?
There's content available up to level cap plus 4 and 8 player dungeons for level 50s. There are also hard mode versions of the earlier dungeons. There will be 24 man raids available but I can't remember if its shipping with them active. The higher level stuff has been tested to a certain extent - remember they have a ton of level 50s already (legacy players from the original launch). Whether there is enough content long term who knows...
