I appreciate that they went with Graces f for the Tales series, though i vehemently disagree with Star Ocean 4

Anyway, some battle systems that have stood out for me:

Wild Arms 4 & 5's HEX battle system: I haven't played these in ages, so i don't know how i'd feel about them now, but back then I really enjoyed this battle system

Divinity: Original Sin 1 & 2: My favorite WRPG battle system, the amount of ways you can use elements and terrain during combat is great, and it's relatively fast compared to other turn-based WRPG systems.

Trails of Cold Steel 1 & 2: Overall, this honestly looks pretty similar to your standard turn-based JRPG combat, but I feel like the ability to interrupt the turn order using special attacks (S-Breaks) and turns having random effects (100% critical, status effect added to your attack, heal, etc) sets it apart enough. Like a few other JRPGs, character positioning is also a thing in this system, being able to walk out of AoE spells before they go off (since they take turns to charge) and such.

Resonance of Fate: Because running and jumping across the battlefield while simultaneously shooting enemies is great. Once you get the hang of the battle system, anyway. Downside is that the tutorial for this battle system is 20 walls of text.
