But it doesn't seem very "RPG-like" don't you think? I kinda wished they were to go back to the traditional turn base style of play.
I don't want FF XV to be too traditional. Anyway this just seems like a streamlined version of having a regen spell. Like if you had a regen spell, you would hide behind something or stay away from an enemy while you recovered. Here they're just not requiring a spell.
IMO it's always lazy design when you use non-spell based, or item based (like dark souls) regenerating health.
However, Xenoblade and Deus Ex HR both used it last gen like someone, and were some of the most highly rated RPG's so it's not the end all be all. But I didn't like that aspect about either game either.
Several RPGs I've played have regenerating health after battle (besides Xenoblade, Baten Kaitos Origins, TWEWY, Crimson Shroud are a few examples). How is it lazy? It's pretty convenient IMO. Minimizes the time you have to spend in menus. I've also found those games on average to be more challenging than most RPGs.
