Ok so espers in ff12 aren't that big of a deal. I will probably have a "main" party that will take part in most of the battles, so I will naturally want to attach the best espers to them. Could I get some suggestions for which espers should go with a melee, range/support, and a mage character? And in case that it really truly does not matter who I assign them to, what are the best espers in general to give to the main party?
