You need teleport to proceed in the main plot? I don't think so.
Perhaps not NEED, but it's more difficult to
reach the Seeker camp without being able to teleport around the exploding pods or move the pods themselves.
And that doesn't change my view that the Teleportation gloves do not need and should not get a use restriction. If Teleport is a problem, rebalance the spell. For example, you could increase the AP use to 4 or 5 so that you need to save up at least 1 full turn of AP to use it.
