Ah yes, the old times argument again.
The problem is we have no bad luck protection in raids, for example, I killed mythic Sire 14-15 times ( nearly 4 months of reclears) only got 1 item from him and finished tier without ever getting my last 3 bis items.
That's so fun, right?
Imo they should just add rolls back so people with giga bad rng can have higher chance of getting loot. That is especially important if they are adding tier sets or dom shard / socket equivalent next tier. Cba sitting on the bench just because I got unlucky dom socket pieces.
