What's wrong asking for esuna/leech after berserk ends though? It's not like I kick up a fuss or anything if I don't get it, it's a nice bonus if I do though. And I do get them from time to time during DR.
But like I said, this came over from my HG / holmgang countdown macro. My healer friend once said she can toss an esuna for me if she knows when berserk is going to end, hence how this macro came about.
