Treantmonk's brief data point for Rogue at 13th level (same level he chose for all classes) went as follows:
Species: Any Dex 17 at level 1
Weapon Masteries: Shortbow, Scimitar (Nick) (could have gone sword with Vex but opted against it due to issues with calculating DPR)
First Level Feat: open (Lucky, Tough, etc.) (No DPR impact assumed)
Fourth Level Feat: Sentinel (Dex 18) (Assumes some reaction attacks with sneak attack sometimes)
Eighth Level Feat: Charger (Dex 19) (+1d8 on first attack)
Tenth level Feat: Skulker (Dex 20) (no DPR impact other than Dex)
Subclass Assassin
Average damage per round came out to 46.5 spread over four rounds of combat (though first round does meaningfully more than later rounds due to Assassinate and Charger, and he spread this over all four rounds rather than counting it just in round 1).
This does not include poisoning the enemy. If you poison them, that's even better.
Here was the most recent DPR calculation I found, though I think there might have been one more and I will look for that shortly. Baseline is a standard Warlock, not optimized for pact of blade. I know Monk is not here, and I know he was very impressed with the Monk changes and will at some point at that. I also know he thought Pact of the Blade was a bit broken and likely to get a fix. Seemed like he thought the average damage for non-casters is around 50, with this rogue coming in around 3.5 short of that not including poisoning.
