My favorite aspect of MMO games is exploration! I absolutely love running through the world and seeing what it has to offer. However, I dislike exploring worlds that don't offer anything for explorers besides more quests and mobs to fight.
One thing I would love to see in 2.0 or post 2.0 would be environmental puzzles. I've played a several other MMO games that have small and large puzzles scattered through the world and add a depth to exploration. Since jumping won't effect combat in 2.0, perhaps jumping can be used for these puzzles so that the feature doesn't completely go to waste. An example I suppose would be a small mountain (8 stories tall?) that you can scale by running, jumping, taking small leaps of faith, etc. Once you reach the top, there could be a treasure chest waiting for you or perhaps some sort of special NM or something.
Other examples can be lava pits with a path of small rocks that lead to a chest, a long hallway with traps sprouting from the ground that can be avoided by jumping, a series of trees that can be scaled to reach the top of a giant tree...you get the idea.
Disregard this thread of puzzles of this sort were already confirmed to be included in 2.0
