Worst pre-expansion event ever?

This is the most alt unfriendly event I think they have ever made. Each boss only spawns a single time per window, which is a horrible design decision. The gap between zones is FAR too long, and even when it goes down to 30 minutes it will still be too long. This barely qualifies as an event, this is just horrendous.
