Good change.
Y'all did watch Blizzcon? They stated that SoD will be more casual friendly than other WoW versions. Did y'all sleep? SoD is a fun mode. If you need a bit more challenges go to other versions maybe upcoming cata hc and if you want to flex with your skill and go fully degen play Retail try to kill Mythic Fyrrak or beat M+30. Let casuals be casuals and enjoy this gamemode. If you don't like it than play other versions like Classic HC or so...
Totally fine with the nerfs, this is classic, not retail, people want to raid for fun and min-maxing/parsing should be optional.

For the record, Shade of Eranikus can still thrash. Got several logs where my tanks gets thrashed, however it not really a big issue if you got an actual tank and not a DPS with increased threat modifier.
