Not sure why folks are wailing about sharing drops with RGE/NIN. It's all but written in the stars that Musketeer will be coming eventually, and that will almost certainly be a ranged DEX class competing for drops against ARC/BRD. If SE decides to bend the rules to the point of breaking to force RGE/NIN to use DEX instead of STR for its moves, that just means that MSK and ARC are going to have to share with RGE instead of PGL and LNC sharing with RGE. Someone's gonna have to share. :P

Regardless, I find the idea of a melee job using DEX as their main stat to be highly unliikely. SE took great pains in simplifying the stat system for FFXIV. In FFXI, the stats had all kinds of crazy hidden effects that were rarely explained in-game; you pretty much had to be a FFXI guru to know, for example, that VIT boosted the potency of Cure spells (not as much as MND or Healling Skill, but still there). In FFXIV, every stat has a very small pool of effects, and those effects are clearly printed on the tooltip for that stat.

For SE to turn around and make RGE/NIN a DEX job would throw that simplicity out the window.
