Since I helped instigate this just thought I'd clarify a bit. I have a player who is using a battle master fighter with the great weapon fighting style that is currently 5th level. I have never seen him use an action surge, a maneuver or reroll damage a 1 or 2 on his damage dice.
I don't know if he just doesn't think of it or is saving them for a later combat that never happens. I reminded him a couple of times, but it's not my job to run his PC.
#1, but for a limited time. After reminding one of my long term players over and over to add modifiers and use sneak attack and cunning action, eventually I just stopped. That went on for more than a year. I’d have more sympathy if he bothered to open his PHB once between sessions to learn and remind himself what his class abilities were.
Do the other players mention anything? If he's missing a good chunk of his class shtick, that would be impairing his fighting capacity, and that would impact the group as a whole.
