That's a really good point. After clearing the easy as piss raids and HM Flash points what do we do?? So i've finished raiding for the night, done all my dailies, And lvled an alt for a bit (I could lvl more but I don't really want to spend all of my time on an MMO grinding lvls all the time)...... Now i'll just spend an hour doing laps of the fleet because there's nothing to do.
The raids are easy but heaps of good fun. So that aspect of the "lack of content" isn't so much the issue I think it's more the little things. Like achievements for example.
