I understand that this is a low priority bug since the warclaw is WVW focused, but I feel like it should be mentioned anyway. The warclaw does not gain the reduced fall damage from the Masterful Descent mastery in many open world locations. I've personally tested with warclaw and compared falling damage percentages to the raptor in two of the three locations (sun's refuge and thunderhead peaks) and tested again with the raptor, the roller beetle and the jackal in comparison to the warclaw and falling from the same height in Divinity's Reach, the warclaw takes more falling damage.
If you join a debate and provide little to no proof when the other side provides lots of evidence, you can't then declare yourself the winner of that debate. Veterans can make signatures apparently.
