how on earth do you find this even close to your #1, CN is a lackluster raid with at best, 2 good fights (mythic only, artificer and sire imo), said first tier raid already lasting like 6 months with no 9.1 date yet, terrible covenant balance, the maw is a joke.
SL isnt *bad*, but it definitely isnt the best. WoTLK, MoP and Legion are definitely better xpacs, with some grey area for others like TBC/Cata.
