Yeah, I'm using the latest patch. All that map contains is a Dummy unit based on Locust. It has it's cast backswing/point set to 0.00, movement type set to None, Speed base set 0, attack disabled, etc.. I think a lot of people forget to adjust the Art - Cast Backswing/Point thus resulting in their Dummy's having delayed casts. A single dummy unit should be able to cast Bloodlust on a Unit Group if done correctly.
