Made a mistake with transmog scroll.

[Grammalour]

Okay so for the first time I got a scroll which lets you trasnmog an item with the appereance of another one. I did it the other way around, instead of transmogrifying the item I want to appear I first clicked on the item I wanted to change the appereance of... Can I talk to someone about this?

Probably not, many many more have done the same mistake, or trying to mog a wep you can't initially use, mogging gray items etc.

Every raid boss in Wotlk - OS - Onyxia - Malygos - VoA - Naxxramas - Ulduar - ToC - ICC, has around (I think atleast after farming 50 ish scrolls) 5% drop chans.
If you want another scroll, go Naxxramas or Ulduar, since they are the raids with most / easyest bosses and therefore a bigger chans of getting one.
