The Human Target
Adventurer
The majority of role players don't get into the details of the math and play what superficially seems fun. The majority of them do not post on message boards. The majority of D&D message board posters are math-centric players.
There is a broad spectrum of choices for weapons for fighters that exceeds an efficient threshold. Outside of choosing a clearly inferior weapon, you're good to go - even if your choice does not rise up to great.
I actually think the opposite of this is true.
Most players who don't get too deep or understand the math are going to pick the biggest dice weapon they can and move on.
