Tales of Graces F has superb combat, even amongst the Tales series in general. It's just too bad that everything else surrounding it is nigh-unbearable. Fortunately Zestiria marks the return of the Graces F combat guy, and the combat was simply that good that I'm willing to give them another chance where they hopefully don't yet again create a story/series of characters that make me want to jam a fork into my brain.
One I particularly enjoyed was Radiant Historia. I liked the ability to group enemies together and wail on them or shove them into a trap. Also, you could arrange the order of your party's moves rather than depending on agility. I'm also a fan of the Persona 3 (portable) / 4 combat (not that it couldn't be improved). If you count Demon's / Dark Souls, then that obviously deserves a mention (even though this site is Souls central currently).
I've been playing Xenoblade and there's definitely something fresh about the combat. The tutorials are clear and you can get comfortable with the rhythm of battle pretty quickly.
Not sure if Strategy JRPGs would count, in which case I'd also mention Valkyria Chronicles.
Also, haven't gotten too far into Etrian Odyssey IV, but I'd like to give a shoutout to the poppin' battle music. That's how you get pumped up.
