What drives a poor reputation for the Rogue class?

[JNAProductions]

A level 8 rogue with 20 dex and a +1 shortbow that deals an additional 2d6 on the first hit each attack action (this is literally an affix my table has added to make up for rogue getting kinda screwed by +d6 per hit weapons) deals 30.14 DPR

A level 8 barb with 18 str, GWM*, and a +1 greatsword that adds d6 damage to each hit deals 37.25

Imma do a spreadsheet for this.

Find it here.

At AC 16, the Rogue is better than a non-GWM Barbarian under these circumstances.
With GWM, they do about 4.5 less damage per turn, assuming advantage.
