This mod adds enemies you mouseover or target in an arena to a list.
This is an ultra-lightweight addon that was suggested to me by a friend.
It works by simply adding enemies you mouseover or target in an arena to a list. At the beginning of an arena match, type:
'/arenascan' or '/ascan'
The addon will then spam ignore on all of the people on your list. If the ignore succeeds, they are in the arena with you. It will then unignore the person and report their name and class into /say in the format:
Due to the fact that sending large amounts of requests to ignore will risk disconnecting you, I've also added a command to clear the list:
However, you'll need to amass a fairly large list before you actually risk being disconnected.
