If the content were more compelling there'd be little fear of players wanting to skip over it. You can't force it and some people just aren't interested in anything but pvp/raiding.
The best jumping puzzles in the game were left behind in Mists. Get to the top of the bridge on Timeless Isle while waiting for Huolon to pop. Jump the electricity maze in Isle of Thunder. Nagrand gliders were a neat gimmick but I don't really want stuff like that to come back unless there's a greedy darkmoon faire guy on the landing pad who will taxi me back for gold.
Although arguably Vanilla had the best jumping puzzles because if you angled yourself correctly you could scale any non vertical surface.
You say that like players won't always take the easy way out if you give it to them. People don't have a problem fighting mobs, it's fun. But if you let them just queue for lfr and get all the best loot without actually pressing buttons, they would.
