I think that one problem is the "weapon = class" mechanic. Why not just let us set which class we want to play and be done with it?
With the addition of jobs, I think this issue is mostly satisfied.
One thing that did seem a tad unrealistic in FFXI was that your skill with a weapon was scaled down, even severely, if you switched to a lower level job. For example, you could be an endgame Thief, but if you job change to a level 1 Dancer, suddenly you've forgotten almost everything you knew about daggers.
At least with a weapon = class system, your skill with a weapon remains constant, even if you switch between its class and job. I'm pretty okay with that because it makes sense. What might be nice for a little variation is having more than one path to a job using different weapons, like Gladiator or Marauder leading to the Warrior job depending if you like using Swords or Axes, or optionally, you can pursue both.
As for Dual Wield
, Square has a long tradition of offering that with the Ninja job. I'm positive that's when it will surface as an attribute in FFXIV. Edited, Apr 22nd 2012 6:10pm by Xoie
