TL;DR analogy:
WoW has a all in one option. You get one big gun, you can fire single shots, full auto, small grenade launcher, flame thrower, and blade attached for stabby stab.
You still need to know which one to use, when, where, how, why, and target + position yourself correctly.
In FF all those are seperated. You can shoot with a pistol, then you have to put it in the bag, grab a machine gun, put that away, grab a grenade launcher, put that away for the knife, again for the flame thrower and so on...
Having this many buttons to press doesn't require "mORe sKiLL"... it just makes the gameplay for the player inconvenient and personally to me, pretty annoying.
