As it always goes, the next patch will the previous raid become obsolete. There is no need to do them because mythic+5 man give better loots etc. It is much harder to organize ppl to enter Castle Nathria which loots are way too outdated.
But you know, I enjoy Artificer boss much more then all different bosses form 5man dungeons. Sire Denathrius is beast as boss. Much more fun. And I enjoy working together with other tank much more then solo-tanking. Or I enjoy much more competition and supporting with other healer.
So, I wonder. Does Castle Nathria really have to become obsolete. Never relevant again into the progression of Shadowlands?
5man dungeons are always relevant, due their mythic+ and sometime their loots get buffed too to keep relevant.
But other raids. Nope.
I would love to see Castle Nathria stay relevant, but as 10 man. With three difficulties. Normal/Heroic/Mythic. Fit into new roster. All difficulties split into wings.
So, I can still enjoy raiding with my characters, as healer and as tank. With loots or anything else that is not totally outdated.
Just random thoughts.
CN 10 man Normal = same ilvl as mythic 5+
CN 10 man Heroic = same ilvl as mythic 10+
CN 10 man Mythic = same illv as mythic 15+
