2 does a piss-poor job of explaining pretty much everything, made even worse by the fact that its combat system is probably the most complex of the four (though Overdrive in X is also pretty unintuitive and not explained very well in-game). Grasping 3 more easily than 2 is not remotely surprising.
While the combat announcements are missing, the voice actor that did those announcements does play a character you'll encounter later (chapter 5, iirc). He's pretty great in his own right.
