I tried it with a couple of groups and the patterns are not really that hard. Just having him targeted will tell you who he is going to attack the minute he does if your close range run underneath him to his back or side step around him asap. Range is a bit easier however it is double with close combat DPS. The only reason we kept wiping was because people seem to have really no experience with the patterns. When asked if how many times you did the previous one most did it 2-7 times. At a minimum people should do the normal one until they don't die or don't use potions. It took me 35 tries to be able to do it with out using potions, and dodging 90% of his attacks.If you can manage not dying or using potions this one is just faster pace with a few new twist. Sure having some MH experience helps too bad you need people for this that actually know what it means to dodge and side step.
