Well gear swaps were simply awesome, and revolutionary in terms of having great itemization in an MMO. It is very unfortunate they have gone away.

Job swaps is not done in battle, so it is not really the same thing. Still the ability to change jobs without a mog house is very good, and does make leveling alt jobs much more useful. I would much much rather have this system than Rift's terrible system of talent tree idiocy.
