Espers are useful as long as you don't expect them to waltz in and lay waste to everything like in FFVIII and FFX. You actually have to protect them. Renimiri is right about one of their uses. They are also good when you want to level one character really quickly.

Besides, Exodus and Chaos are incredibly useful since one is non-elemental and the other can use all the elements (except for earth if I remember correctly.) Ultima is pretty good too, which is good since it's damn near impossible to meet the requirements to use her ultimate attack. I have yet to get Zodiark though...

They're useful, they're just not the "end all, be all" like in past games.
