There was a macro for heroics which I've seen a while back, but cannot seem to find via search.

One of the lines was:
/target Icy Tomb

But there were a few of those /target commands, which make certain fights much easier.
Unfortunately I'm getting "too common" a term to search for here.
And only hits with Icy Tomb on the google search.

The thread I'm thinking of had /target for 3 or 4 things.
Don't really even need a thread link, its more the /target lines.
