So in conclusion, the typical launch tier consists of 17 bosses.
Over the past few expansions (Mists, Draenor, Legion), Blizzard had intentionally been giving the first half of the initial raid more and more time to breathe before opening the gates to the second half, which I actually somewhat agreed with.
But by the time BfA rolled around, the gap was too much. They finally flipped the switch and snipped off the second half of the first tier, moving it into its own 'tier'. Dazar'Alor clearly could have been that second half. Uldir was not a fun launch, and frankly I lost interest and unsubbed before the next raid came out
You did indeed stab me in the back. However, you are only level one, whilst I am level 50. That means I should remain uninjured.
