Scroll Of Purification drops.

I have realised that, for whatever reason, the "Scrolls of purification" (the ones that REMOVE transmog) do NOT drop from any raid, BG, arena, etc. AT ALL.

if someone farms the scrolls of illusion and transmog a set, and then they decide their set looked better WITHOUT the transmog, the only options they have are either farming the entire set again (time consuming, hard working and extremely painfull just for a transmog removal) or donating the scrolls of purification.

considering the scrolls to implement transmog DO drop from raid/bg's/arena, shouldnt the scrolls to REMOVE the transmog drop as well?

maybe it could be implemented something like: "whenever you get a scroll of illusion (tmog apply) you have a chance to get scroll of purificaion (tmog remove)" making extremely rare, but obtainable.

that way you can still remove the tmog WITHOUT re-farming the set or donating the whole thing, but it would still be hard to remove it, making any tmog choice something to be taken seriously.

NOTE: i do NOT mention the scrolls to transmog LEGENDARY items because i DO believe they shouldnt drop, not messing around on that topic.
