Spoiler alert for non-vanguards up here. Not too many of you on the forums here from what I've seen but hey, if you follow the story, this is your warning.

Figure I might bring this up since I went back to this thread from long ago for one of my statements and re-read some of what Nick had said.

The part that's standing out to me is the "New Tier 3 Boss". The wording is as follows: "A new mission arc will be incorporated following the events of the Firestorm Citadel that will include a new boss monster for players to challenge."

Now, with the missions that have been added, we have a direct aftermath to Firestorm Citadel, and directly fight Herex. He is inside a depth marked with the "boss" icon, has the boss theme playing as we fight him, etc.
But my question to all you would be does he count as a boss? I've always imagined boss monsters being ones that give special tokens upon defeating, and are also in the arcade. Herex is in neither of these situations, however he does fit the criteria Nick set forth in that old post.

However, the way it's worded, we could potentially be fighting a completely different enemy. We could be venturing into the core and fighting a boss monster in there perhaps. That is still "technically" tier 3, and the core could simply be depth ???. This could be introduced in every arcade gate, thus not requiring a new gate into the mix or forcing one boss monster gate out of the equation.
Bottom line, do you think Herex was the new boss hinted at in September 2013, or do you think it has yet to be revealed?
