In the Hero Panel, under "Build" and "Weapon Skills," all available weapons to your class should show the full chain of attacks in the tool tip. For example: A Guardian's Greatsword skill 1 chain is: Strike --> Vengeful Strike --> Wrathful Strike. However, in the hero panel under the aforementioned windows, only the first attack is shown (Strike). This would be useful when reviewing your build to see if a particular weapon type would work with it or not before you actually bought the weapon. I understand there is a wiki, etc. that can show this information, but having it in-game would be convenient - especially for those who may be using one monitor.
