Changing Tactics?

Things have gotten interesting in Radiant Historia. Just when I thought I had the battles down to a science, a few curves have been thrown my way.

First, Raynie learned the "Rush" technique at level 25. This attacks the whole front row of the enemy (likely in one swoop of her spear). Then, at level 26 Marco learned "Trans-Turn," a spell which looks like it has the same effect as the "Change" command. But, since it's a spell, it probably does something ever so slightly different, or at the least allows for a variation on the "Change" tactic.

Add to these developments on my end the fact that enemy formations might actually be important for them. This is something noted when the blue Granorg defenders kept forming into a triangle, though this didn't make them do anything different. Perhaps it means that enemies will soon be able to attack all of my party at once, so long as they're in this formation.

Or, maybe it's just a pointless military trick.

Because the entirety of the soldier timeline has (surprise, surprise) so far taken place on the front lines, I keep expecting there to be some sort of RTS mini-game, or maybe a tower defense sort of thing, like in Final Fantasy VII. But, as I play on, it seems that the battles, though the they're in the classic turn-based RPG style, offer room for strategy enough.
