So as the title says, is the game still fun and awesome for you as it was when you first started playing/leveling?
I hit 80 recently and I am enjoying the game, only problem is that there's little incentive to go back to the lower level zones..very rare for you to get a level appropriate drop and the zone completion rewards don't scale to your level. As for dungeons, the only explorable mode dungeon I've done is AC and the path I went down is almost impossible because of a bug. You can't hit the burrows properly in a certain encounter...keeps saying miss and we get overrun eventually.
I haven't been to Orr yet so I can't comment too much on things like DE difficulties at 80...I want to wait till theres more level 80s to go there. I've heard it sucks right now because of lack of people.
