I don't mind Teleportation either, my tiff with it is that:

1) You get it from level 1, friends can take you anywhere in the world and you can get those crystals too without you having to have it beforehand.
2) Hand-holding when everyone and their dog can do it for no reason.

Marauders have the magical power to teleport themselves across the world, with no lore to explain such reasons for said ability. It makes no sense. However, if the Marauder went to an Aethryte crystal, which in itself has the ability to teleport you to any of the other crystals, it makes more sense. It would also add to why your anima gets drained whenever you use it.

I actually kind of miss that White Mages could Tele and BLM could Warp. I liked that in FFXI a lot. Yes, it sucked trying to find someone to do it for you, but there was always the item-usage alternative if you were desperate.

Plus it was a good way to make money >_>
