This bug has brought in a new layer of gameplay in MCOC and I think it's fantastic. While it is a bug and will likely be fixed at some point, I do want to petition the game designers and the game team to take a second look at the functionality of it.  It's very fun to pull off and satisfying visually, and I think would make a great addition to an already great game.  

I propose tweaking up the timing a bit so that it's a little more difficult to pull off, so that skill can enter into the equation and make it an excellent way to reward a practiced summoner!
