A few things that would give the game added depth.

    1.A Tavern/Inn were you can go sit in dull candle lit rooms and order mead and ale along with dripping and meat over the bar.

    2.You see those large shiney buildings and you think wow i wonder what its like in there, could we possibly explore these Castles,battlements, town halls.

    3.Who wants a job? What about applying for little jobs in towns? Hunting for meat for the Tavern or bringing ale from the suppliers, or joining the Ascalon army and gaining a uniform and rank that means something. These jobs would have weekly/daily requirements and you would be paid after a few days.

    You should be able to make your own hair and face and body so that it differs from everyone so like your a warrior you can be 6 foot tall really skinny and have a mop head of hair plus you should be able to make your own armor with your own designs so that it differs and shows differences and you should be able to have different capes in the guild it also would be cool to be the bad guy let the people have a choice and let their dark sides reign free it would be cool also if when you hit a monster you see blood squirt out or something. instead of being only to be ressed if your teammates have one make where you have to like fight through hell or something so you can still come back even if they don't have a res and if they do they can still res you.

    Depending on how far a player gets with their Hall of Monuments in GW1 determines the strength, attributes and skills of dragon/demon/boss they can possess in GW2 PvE persistent areas, and the Mists. When boss dragons appear in the PvE persistent environment, allow some of these to be controlled by players from other realms. [Or allow players to use Tokens of some sort to launch a Player Boss.] The higher a players HoM standing, or other title, the more dangerous the dragon they control becomes. When a Player Boss appears in a PvE enemy realm that player can start laying waist to towns, outposts and villages, until stopped by the the local server population. They can even group up with other controlled Bosses to really challenge a server. Similar to the Ursan Blessing, you would need to keep killing or you'll run out of life, giving the controlled Boss a life span.

    This would help Bolster sales for GW1 prior to the release of GW2. At some point, players not having played GW1 would be allowed to participate, be part of the Havoc (or whatever) system.

    It sounds like they're going to give the ability to swim, which means opening up rivers/seas/lakes/oceans and such as potentially explorable areas. This means that we can have large rivers splitting areas (a real Elon river for example, or changing around the shores in Kryta), or even reachable islands. It also means that we could have shipboard environments. I'm not talking about changing this around into a naval combat simulator; any more than having castles changes it into a medieval siege warfare game. I'm talking about being able to take the occasional cut scene from Prophecies and Nightfall that took place on ship (as we were moving from one region to another) and putting them into full game play.

    You could have ships that ferry in game time from mainland to an island. Maybe during the ferry, a sea creature attacks. Characters could attack back, get knocked into the water, have to swim back and climb into the ship or try to attack in the water. Or you could have a quest to retrieve something from a wreck, and you could charter a boat out to the wreck, and dive for it, using a spell to hold your breath. Just some thoughts on what could be doable.
