Enable Ihsgard and Ala'Mhigo as Grand Companies
Just a thought, but competition among companies might give the players more immersion.

Enable the speed-run tab and ranking
An interesting thing about running an instance again is trying to clear it with extreme efficiency and faster, every chest needs to be opened, every corner explored and every monster killed, so this would be a game mode where people would try to finish a dungeon (synced) and tell which party dealt higher damage per second, lowest damage and most efficient healing (that could be another fact that would build more statics).

An in-game tab for server ranking
Who is the richest? Biggest networth? Best gear and numbers of content cleared? Grand Company rank? PvP ranking? Should things could be accessible in-game, that would reward winners/try-harders and engage more competitors.

Funny enough, the Darklight tanking set had that in 1.2x:

Wow that's neat. 1.xx had a lot of more details etc, but it's funny how they wanted that to be on ps3 when 2.xx barely worked on it haha.

We called it "Frontlines", and until they offered XP, much of the playerbase convinced themselves, often without trying, that it was "toxic", had "too many buttons", was poorly balanced, and avoided it like the plague.

Believe it or not, it's worse now than it was before, balance wise.
