[@MelonHead], I don't think gravity should be on that list. In that case you could say any type of magic, like advanced fire magic that spawns at your opponent's location at a glance. Time and teleportation is more inherently op, although any type of magic wouldn't be with certain restrctions. We're assuming a whole lot, but of course its much easier to generalize magic types rather than list all the possibilities.

Like I said, most powers [b]can[/b] be raised to the extreme at which it becomes non-interactive, and therefore broken. Most are expected to have a travel time for this reason, but gravity manipulation is usually direct, you change the force of gravity acting directly on a person, which can quickly allow you to kill them. The ability to generate fire on a person's location is also an example of an ability that is overpowered at any level. Sure, many higher tiers might not be overly bothered by fire but if they were they would die without being able to interact with it.
