I never finishe EOTN, I quite liked it though, I thought there was a good variety of quests and at least the bits of it I've seen were really really polished, showed of ANet's experience at designing PvE content to the full. I also thought the solo bits were quite imaginative (you know, stuff like 1v1 tournaments against mobs) and gave you free rein to come up with silly unusual builds to get through challengers that would have normally been quite a challenge for your class 1v1. At some point I'm gonna go back to it, get my Black Moa minipet and muck about with all the OP pve-only skills they introduced in EOTN and factions to see how sick a build I can come up with
Unfortunately, the GvG metagame seems to be a bit stagnant atm which makes it boring to watch, so I don't see myself ever getting into a GvG guild again. I'd love to do some more HA, seeing as you can pug it to an extent and don't need to play every day if you don't have a guild depending on you to be online so they can field a team, but I reckon it'dbe hard for me to get a decent group, cause I stopped doing HA way before they turned it to 6v6 so I missed all those double fame weekends etc. I was r4 I think before I quit, and I'm guessing by now even the scrubbiest of scrubs will be r9 and I'll be consigned to the bottom of the pile begging for a place in the crappiest of pugs.
