Everyone's literal second-favorite poster
I always found brutal a little boring, honestly. It's a (0.5* number of dice) damage increase per brutal point, and it just lowers the variance of the possible results.And I'll second the "brutal" suggestion. That feels much more in keeping with the great weapon fighter concept:
I prefer advantage, because it minimizes the chances of whiffs and increases the chance of seeing max damage by almost double. Plus, it favors rolling bigger dice, which makes it even more fun.
