It is not that simple with BW, they seem to be much more random when granting PTS access. When my guild submitted for Tyth, about 40% of the people didn't get invites, making any sort of sensible fight verification impossible. After our pleas to grant access to missing members were ignored 3 or 4 times, we simply stopped bothering. I wonder how many other guilds got a similar treatment, thus denying the devs potentially valuable feedback.
All in all, yes, the fight ended up too easy. Especially considering how long people needed to kill Brontes NiM or Revan HM on release.
