Yes, it's as ispano said. http://en.wikipedia.org/wiki/Rogue_%...acter_class%29
It's also simply that DEX doesn't affect ranged damage in this game even though the tool-tip says it does. There are plenty of weapons in the history of video games that would classify as using DEX as well that they could add to this game. To make them use STR just doesn't sit well with me. And then you have all the possible ranged attacks they could add to our existing and future melee classes and jobs but they won't be using DEX as the tool-tip suggests they would. It's messy this way. It's much neater and accurate for the tool-tip to just specify the weapon type that the stat gives AP to.
There was a lot of misinformation going around when the game was launched due to people thinking those 3 attacks were based on DEX. In fact, Tomahawk at least (and likely the others) WERE based on DEX when they were added. It was only after the devs realized in doing this they made the attacks useless (the classes were put on STR gear and their AP scaled with STR). Now attacks just use AP and AP is derived from either DEX or STR depending on the weapon type you have equipped.
