The year has just begun and more update content for the WvW has already been announced. The Jadebot also has a lot of potential for updates, but everything takes time and testing phases are also necessary. First wait, then complain.
But the workbenches would be really nice in the cities (was even announced somewhere on the outskirts times, just can't remember exactly where). Presumably too few players still use the Jadebot, so it has been downgraded in priority.
Yeah, it's really fun. The view in the grove from above the leaves is beautiful :)
