One of the most frustrating things about the current world event is opening a rift and its fire/life/air or earth.
I have actually seen a few people complain that they spent an hour trying to get a water rift to open and when they raced across the zone by the time they got to an open rift, it was closed.
There should be items you can buy off the vendors for each faction that you use to open a rift of a certain type, but it costs you planarite to do so. For example, the order of purity would sell the water one and would require a certain level of faction.
So for example, you come across an unopened rift, instead of using your regular planar lure, you use your special water lure, it charges you 100/250/500/1000 (whatever is reasonable) planarite and it opens up a water lure instead of a random element.
