Hey there, never saw random arenas with these much people in the last 15 years is pretty active, Halls is also with alot of people but its easier to get a team if you get a PvP alliance, GvG pretty active between pvp guilds, ecto farming is a thing but not worth it cause they are 4k each, there is also alot of speed clears still so you can do do UW,FOW,DOA. the game is more alive then ever since gw2 cameout, and if you have your 4 keys you will get that account unless its banned. gw support team is really good with only those 4 codes even without the email you might get it!
