Feedback:User/I approve this pwn/world instances

Have multiple types of instances of the world, each instance having different rules, gameplay types, foes, objects, game mechanics or whatever players want. This multiple type of instancing can be applied to gw1 also. New Instances can be used as large updates to the game or to apply changes to gameplay if things become stagnant, repetitive, predictable or just plain boring (maybe) after extensive repetitions of the game. Or if people just want something new. Some examples of different types of instances would be: non-persistant private worlds with henchies, role playing emphasized worlds, beginner-novice-intermediate-advance worlds, realistic mode worlds, friendly fire damage capable worlds, extra dangerous worlds of some sort, free for all with everyone vs everyone worlds, economy mainly based worlds, more strategy and tactics base worlds with base building gameplay type of mechanics or storyless worlds. The sky is the limit. These worlds don't have to be interoperable either for that matter. In addition, players can choose whatever flavor of gameplay that they would want. They can change between characters and worlds to their choosing. Or if the case was, they just became bored with one. This might be beyond gw2 scope but its a shot. As extra motivating incentive, players can look forward to playing their favorite gaming style when it becomes available with new updates.
