Wow is a game that uses a faster gcd than ffxiv. Attack speed is not the issue as Wow skills still feel a helluva lot more impactful than ffxiv.

A fury warrior in wow felt like a berserker thrashing the foes, a monk felt like a martial artist who crushed the enemies bones, a paladin felt like a righteous crusader vanquishing evil. i could go on.

In ffxiv on the other hand, nothing really stands out. Lets take a strong attack.. Rage of Halone. this attack feels weak as all you do is flail your sword as if it its weightless while making swishy-swashy sounds. you cant hear it hit the enemy.
the monk equivalent would be snap punch. this ability sounds awesome right? youre punching with a snap. you expect to hear that but all you get is a "thud" while doing a funny pose. no crispy, satisfying attack. no snap. just a blunt thud.
