Hi. I returned after ~16 years. I started with Nightfall and shortly after bought Proh/Factions/Eotn and stopped playing around early 2009. Beginning this year, I found my old game boxes with access codes and asked ANet to recover my account (I didn't have my password any more), and to my surprise they did that after asking some more information. I created a new main, mesmer this time. My previous main was an elementalist, but I didn't want to depend on enchantments any more since enchantment removal is ubiquitious. And mesmers got a lot better for PvE while I was away. GW made me guild leader of my old casual PvE guild. all other players are gone. But since the guild has a fully upgraded guild hall, this is now my private "home".
I now try stuff I never experienced "last time", like doing DoA, Urgoz or Eotn dungeons alone with heroes. This week, I did my first time ever HA, which is now pretty much PvE as well, since most teams seem to be bots or single players (like me) with 7 henchmen. I even got to see the Hall of Heroes some times, standing no chance against teams with multiple human players - but it was nice to be there anyway. This was out of curiosity, my focus will be PvE. But now I have some Z-keys as a "souvenier".
