I didn't like the damage system in BoL when I first read about it.   I derisively just thought it was damage advantage/disadvantage which is no big deal as D&D 5e has had a roll more/keep high or low for over 5 years at that point and other games had probably done it prior too...  It's only now when I was brainstorming how to come up with a damage system for a rules light game myself that I realized that this solution meets most of my criteria (mainly a difference between weapon classes while still not overly penalizing the potential of lighter weapons while still being simple to understand and easy to calculate) and was deceptively elegant in its minimalist design.   Mind you... I might have come to the conclusion sooner if I had actually played but all my experience with the game has been theoretical at this point unfortunately.

Anyone else have a similar faux epiphany about something in BoL whether about this mechanic or some other ones?
