Playing as a Guardian I noticed that when I have a sceptre/focus combo equiped the stats are not contributing to my reported attack value. When I swap between my sceptre/focus and staff I see my Attack value drop by about 100pts even though both weapon sets cumulatively have the same stats.
This happens with transmuted and non-transmuted for what it’s worth.
Not sure if this is only a display bug or if this is having an actual effect in game.
