A shorter re-spawn time would make it far more enjoyable - or a *Hint, letting people know that they may have to wait for Hakra to make an appearance.
Whilst I waited, I had time to come to the forums as we thought it was bugged, chat with other people who where waiting and also thought it must be bugged and eventually, Hakra spawned.
Sadly, as there were a few people waiting, some were not quick enough to get a hit in so they had to wait again.
Omg...I just got there. About 50 people were waiting for the respawn, when it finally happened the guy was dead in about 5 seconds. It was one of the most awesome things I have ever seen.
