Welcome back, Not sure if it is still going on, but there are some nice 5th Aniversery Events going on right now. They are doing the skelly armies thing again. Every game night in EC, QH, BB and SF. Kill commanders for decent loots. Also they have replaced a bunch of old mobs with "Fabled" versions that drop enhanced "Fabled" versions of loot. Other than that, not much going on. Hope you missed out on all of the protests and train bombings while you were abroad.
Glad you made it back safe,
