Sounds like ffxv will be Kingdom Hearts in an FF skin
That's a rather unfair simplification of the XV's sophisticated battle system. In my opinion that comparison isn't giving it enough credit. The changes Tabata has done are adding something even more it's own than it was before. Factors now at play between character placement vs enemy placement on the battlefield. Not to mention how the XV's battle system is utilizing the dynamic weather system in gameplay through spells. In addition to the that the party's output can suffer they don't rest up. A pretty clever mechanic that references the reality element of XV. Not to mention all of the unknown mechanics or elements that haven't been shown off yet in their proper demonstration.
It seems those saying the gameplay is some sort of KH reskin are either not understanding or noticing all the nuances at play with each other.
