… is an extremely lackluster feat. I had originally read the skill description as being a main OR bonus attack and that felt really strong. After getting the feat I am now stuck with a meaningless skill that takes both actions for what is essentially just a walk + hit.
It's certainly a niche ability, but it does effectively function as a Dash action + bonus action Attack with a +5 bonus to the damage roll and an unlimited # of uses. For races with reduced mobility this is almost the equivalent of gaining Cunning Action Dash with a feat. It can be about as good as the +2 ASI on certain builds.
The bigger issue is that it's competing with feats like GWM, Sharpshooter, and Tavern Brawler. So it just isn't worth picking up until much later in the game and only on builds with at least 3 feat selections.
