A giant post from the creators of gw1 areana.net was posted about how they plan on making guild wars 2 amazing.
The biggest part of this is how they plan on giving all players xp in the game. If you participate in killing a mob or a giant quest you will get 100% of the xp and loot all the other players get. Its not going to be split up based on the amount of damage you do, or getting the finale blow. This is their way they think to fix wow instances and the random loot rolls all players have to deal with. So instead of being forced to do an instance 50+ times to just get a few items you need, now you can run it far less and get all the great loot. Here is the direct quote in the blog about this subject.
Of course GW2 has great support for parties, but they just don’t feel as necessary as they do in other MMOs, because your interests are always aligned with all other nearby players anyway. When someone kills a monster, not just that player’s party but everyone who was seriously involved in the fight gets 100% of the XP and loot for the kill. When an event is happening in the world – when the bandits are terrorizing a village – everyone in the area has the same motivation, and when the event ends, everyone gets rewarded.
This sounds like a very promising way to handle mmos. However the big problem is the end game. What keeps wow players playing is trying to get all the top tier loot in the game. From Guild Wars 2 new loot system it seems players will hit that limit far quicker, so they need to find a way to keep players coming back. Maybe dungeons dont drop as much loot, or more end game instances? Well i have faith that areana.net has learned all the pros and cons from guild wars 1 and they will release something great.
