I searched a few topics but none actually give an answer to what I want to ask.
You see, I used a BoE stone to upgrade my Guild Herald on the Alliance side (I have each factions Guild Herald/Paige/Gruntling/Squire), but it did not upgrade my count towards that +1 Rare from Uncommon.
The item shows completely blue in rarity and everything ingame. The closest reply I found is that it shows the rarity of the item? But that's ridiculous since it was in fact upgraded... I don't know, just annoying to have wasted a BoE stone, to have passed it cross faction so that I could first upgrade the opposing factions first...
Well any reply with actual facts is welcome, because I have not found any answers and it's frustrating.
