Guild Wars 2

I have a lvl 80 elementalist that I was gearing up with a full set of “Superior Rune of the Elementalist”. I placed the first rune on my armor and it immediately filled out all 6 runes bonus slots and reported that I had “7/6” runes added. I thought this was weird but figured it might straighten itself out. By the end of everyhing, I had “12/6” runes. I have attached a screenshot.

This is because if you haven’t changed your runes on your spvp armor it counts those in as well (and you start with a full set of “superior rune of <your class>”)
This is PURELY a visual bug though the actual effects you get is as if you have that 1 rune you equipped only (or however many runes you equipped) on your pve armor

Thanks for letting me know that. I had no idea as I’ve yet to touch the PVP side of the game.
