Bottom line is that we just did whatever we felt like, didn't sweat "progress" towards some ridiculous virtual goal, and mixed it up with different characters and events. In that 3 hours, we played four distinct game-modes, with 3 different characters each!
We started with an AC run, which was fun because we did a few things that we hadn't done before, rather than just speed-running it, and we had a few newer players to help along.
Then we went to EB to the jumping puzzle, which I'd never been to. It was a hoot. Didn't get far at all, but had some hilarious 3-way rivalries going with some FA & TC guys: yanking each other around and blasting each other off cliffs. Eventually, more TC showed up so we couldn't progress. Next time!
So the two of us ran around EB being obnoxious: taking camps, jacking yaks out from the middle of small zergs, stealing sentries, or drawing zergs to defend keeps from our two man "attacks". As a mark necro and focus mesmer, we eluded many zergs in some pretty epic chases. Didn't "accomplish" that much, but had some really fun cat and mouse going.
Finally, we dropped into tPvP, where we won our first tournament (we don't play much). We were mostly carried by a helluva thief player, but my brother and I had fun playing a psuedo-bunker-duo with strong team-fight builds. Our teammates were very nice people: didn't even complain when I bombed our first match (15 points maybe?)
So in 3 hours, we did a dungeon, ridiculous jumping puzzle + pvp, hit 'n' run WvW with some really fun chases (we had a group of 4 TC guys chasing us around for nearly 20 minutes), and a tPvP tournament. Never got boring, never felt grindy. We didn't really make much "progress", certainly not compared to focused grinding, but we had a lot of fun!
Much better than mindlessly trying to grind out some achievement, gear, or whatnot.
