I'm not sure if I understood it well, but the "gambits" are what leads to the directional input + attack button actions.
But that's only for Noctis, yes. The "gambits" for other characters will be controlled by the AI.
from what i'm underdstanding, i dont think gambits will be the same for Noctis attacks, but it'll be more of a building a balanced deck of weapons or unbalanced, whatever people enjoy, like a full deck of great swords, or rapiers, lances, etc, while the directional inputs + attack will be for specific stuff you may want to use during battle, the same for the special button, and this is just for the weapon stuff with noctis, theres still stuff left to know how it will work, like magic and summons
and yes the gambits are pretty much left for the AI, the player will customize every character to perform specific actions and then leave it to the AI during battles, while those noctis + party member moves will depend on the player, etc
Can you even be sure of this? It wasn't stated one way or the other, and it seems just as likely that Noctis is auto-targeting and warping. I don't care if the game is difficult or not, just holding down X for your super move is pretty lame. Slide dash doesn't seem like a good comparison at all. That was just a closing move that led into combos you had control over, a single button-press distance closer. The comparison to the ghost drive form where you auto teleport and mash X looks a lot more apt, to me.
well we never see any kind of lock-on icon besides the long warp one, but we can assume that the player is manually targeting enemies, other than that i do agree with you that holding down a button for auto-combo stuff is really unsatisfying and hope they put the option to press for each individual attack
