I've been having the problem that my Details icon as a Holy Paladin is being detected as being Protection - not just by me, but also by my guildies (i.e. they see me as Prot as well). The other Holy Paladin in the guild has reported the same issue. This doesn't happen for any other class/spec as far as I know. It also doesn't happen 100% of the time, but always in raids, only sometimes in dungeons.
Unfortunately I can't post links since I only made my account here to share this, so add this to the end of a normal imgur address and you should see: /a/skEkr
I checked the Details.lua file under SavedVariables of that encounter and it shows this for both the tank and I.
Code:["spec"] = 66,
Let me know if you need anything else from me!
