Everyone remembers the BG exploit, where you could join as if you weren't actually in it by using a macro to Accept and Decline at the same time. (Recently hotfixed.)
Well, since 2.4 has came, there's an idea I'd like to try, I'll test it using my own badges, in case it doesn't work.
When you goto a vendor that requires a tier token, or badges etc and try to buy an item there is a window that comes up that says:
"Are you sure you would like to exchange xxx for the following item?
[ Yes ] [ No ]"
Well, if someone could find out the script for when you click yes, and when you click no, there is a possibility we could get a ton of free stuff, including all your sets of tier with 1 token, free badge gear, free honor gear, arena gear etc.
