What I'd like to see is add some specific rewards only achievable by being good at something. An example would be adding a loooong and tricky jumping puzzle, where the reward wouldn't be a random chest but a nice looking weapon (skin) (specific one). Or maybe bring back the Bell Choir and have us play a looong and difficult song and again reward us with some nice cosmetic stuff. Possibly even quality stuff, but exotics aren't that hard to get and I guess I'd be asking for too much if I said Ascended gear. Some armor skins would be nice as well. Say make the reward of the puzzle or whatever reset every week and allow players to choose their reward = 6 weeks for some epic full armor skin.
The thing is that currently you just need to almost brainlessly repeat a task over and over again to get what you want. Want a dungeon set / ascended stuff / Gift of whatever? Keep repeating the path over and over again till you get enough tokens. Want some lodestones? Keep killing elementals over and over.
The whole point of the "skill challenges" would be that one success is enough. No need to complete the thing 100 times to get the reward.
