Guild Wars 2

Simply put, I would like the mission mode from guild wars 1 to be reintroduced, but doing it using your order.

So, in your order instance you could have a npc to talk to who sends you out on missions (or as you rank up) who you talk to to get the latest information.

This would then send you on themed missions for the three orders, which would just be your basic flavored missions/dungeons.

They could reward: Order themed gear/weaponry, providing an alternate way to get your uniform. Perhaps with lower stats than the higher tiered stuff and different appearances or variations.

They would be as follows:

Priory Missions – Explore ruins, indiana jones style. Lots of traps, jumping puzzles, puzzles and general adventure feel to them.

Secondly, scholarly missions – Researching artifacts, experimenting on creatures, researching creatures and lore based missions etc.

Whispers Missions – Assassinations, stealth missions, espionage and spy as well as scouting missions. Stealing technology and so forth.

Vigil Missions – Simple war missions on the front lines and all around Tyria. Escort missions, siege missions, outright army vs army clashes and general fighting with big bad enemies, survival missions, etc.

etc.

With the missions giving the theme of your order, perhaps some npcs to talk to and interact with that discuss your missions or latest thing.

This would just give you the option of levelling without doing the personal storyline if you so choose, down an alternate path where you just stick with your order and interact with them.

It would also give additional content for everyone to do and another reason to go back into your personal instance of your order.
