Death Sting, will be a Dagger rogues BIS for PVE, allows them to Drop Age Core Leather Gloves, and pick up an easy setup for 4 set Darkmantle which is stupid broken at current, allowing for a mix of sets well into Naxx,without Death sting a PVE rogue is stuck with ACLG, to get the minimum 8 weapon skill to reduce the glacing blows.
No mention of Scarab Brooch?
Scepter of the False Prophet? :P
No mention of Sharpened Silithid Femur and Royal Scepter of Vek'lor?
The Scarab Brooch was a unique trinket with a percentage ability (15% absorbs from healing done) that worked all the way up to lvl 80. I believe it wasnt until Cata that it was nerfed to be less effective after lvl 60. It might not be BiS but the fact that its a unique timeless/level less trinket should make it onto this list.
The fact that Scarab Brooch isn't on here is a sin. It is an item shamans can use even into BC to shield the raid pre-pull. One of the longest lasting items in the game that is obtainable in Classic. S tier at that
