What has changed
There were no changes for 9.2.5 for Assassination.
Not much was done to Assassination directly with patch 9.2. Blizzard introduced new borrowed power systems, primarily the addition of tier sets and the ability to equip an additional legendary alongside your covenant legendary of choice. This patch's combination of borrowed power changes a couple of things around, so let's get to it!
Assassination is often regarded as the go-to raiding spec for rogues. It is a versatile spec with very consistent damage across the board. It is very rare to see Assassination in a bad spot, and due to the nature of the spec, it will often see some sort of play in the mythic raiding scene. Unfortunately, rogues are still missing raid utility as a class, which is invaluable in high-end mythic raiding. Assassination is not very strong at AoE damage, and it mainly focuses on consistent single target damage with short cooldowns to enable strong priority damage.
With 9.2, we see a further push towards this playstyle of strong single target capabilities. You may not always want a rogue in a mythic raid, especially for the high-end compositions. However, if you're looking for boss damage, Assassination will not let you down!
