I equip 5 pieces of armor with the rune and attack the test dummy with an axe on auto attack. Chop, Double Chop and Triple Chop fire for 80, 86, 91 respectively, over and over. I then activate Signet of Might and my attacks jump to 83, 89, 95. Rinse and repeat until the test dummy dies.
I then equip the 6th piece of armor and my Chops again hit for 80, 86, 91, as expected. When I activate Signet of Might the Chops only hit for 83, 89, and 95. These are the same values before equipping the 6th piece of armor with the Superior Rune of Strength, so it appears the 5% bonus to damage is not being applied.
Additionally, during all this equipment swapping my benefit status from the runes ended up being displayed as 8/6. This remained even after logging out to desktop. It appears to only be a display bug, however it could be related.
Furthermore, in both cases when Might fades my Chops drop down to 77, 82, and 87 for a few cycles. These values are actually LOWER than the Chop values before Might was cast. This is most likely a bug with Might itself.
