Ehh, I think that's up for debate. It's better than the version of the battle system featured in the PSP remakes of the Gagharv Trilogy games, but the original PC Gagharv games use a real-time battle system that's pretty unique among JRPGs (even today), and I admittedly was a little disappointed to see that the real-time elements were removed for Trails when I first started playing it.
I've gotten used to the turn-based nature of Trails now, and the amount of depth in the battle system is pretty astonishing when you really get into it... but there are days I still find myself wishing that Falcom would go back to their real-time roots with this series, much as there are days I find myself wishing Falcom would bring back the bump system in Ys.
I guess sometimes, the classics just stick with you.
