I agree with T0rin. Also, how can you look at Blizzard II as a justifiable bind? It's a 4 sec duration lol Tri-Disaster is 5x as long with 20seconds, which makes it extremely useful due to the fact that putting one or more enemies out of commission for 20seconds can make or break an encounter, depending on the content. I've always looked at it as an AoE Sleep with a slightly shorter duration that deals damage lol
