Odd Eye brought up a good point when he said you can only control one character at a time. perhaps a way to select 2 or more characters and make them attack at the same time or perform a sort of special combo.

FFXII has combos. i wouldn't know because im getting it later today but my friends brother told me about something his friend did and said he did some ridiculously high damage for the point of the game against a boss from a lucky combo.
