There needs to be a longer time between when it says the boss is looking for targets and when the bubble appears. Or, killing the Eye should give your entire party the buff, not just one person. Little things like that I think would help a lot of people out. It is a pretty frustrating fight, and a lot of times it's frustrating in an artificial way. Like if my team is doing fine but the Eye screws us over with a weird spawn. That's the game screwing me over, not me screwing up.
