The amount whereby 2WF specialists will be affected is being somewhat exaggerated by some people in this thread, as far as I can see.
For example, the fact that Fighters will be able to compete with Rangers in the 2WF area is more of a (needed) boost for Fighters than a Rangers nerf. There is no reason at all why Fighters should not be able to attain top-notch 2WF capabilities.
Those who will be most affected are people with a Ranger 6 splash with an otherwise non-mêlée focused character class, which is actually a LOT of people -- so that it's understandable that so many people are overreacting.
