I'm aware, but considering that GWS is weaker overall than Dueling, especially in a no-GWM setting, I don't use that ruling.
I would rather incentivize paladins to go S&B, just for aesthetic reasons, so I'd be inclined to follow the sage advice on that, but paladins aren't really common enough in my games for me to really bother either way. Different rulings apart, GWS can also be appealing to the crit-fishing champion, in a non-GWM setting.
My curiosity is for a project more extensive than just nerfing a few feats. I just want to make sure that a lot of the combinations of features that are widely used don't have some large deviation in effectiveness I'm not aware of.
And maybe beefing-up some lacking feats that are currently being ignored would be under your radar, I guess? To that regard I would draw awareness about that "savage attack" feat, as it works weirdly. This feat delivers more impact at lower levels when martials are limited to one attack per round, and can even be an attractive for a variant human fighter for a low level one-shot, when they know beforehand they will never play past 4th level. I wonder why it was designed that way, and what would make it more competitive with PAM, GWM, sentinel or SM. Maybe just allowing it affect all attacks?
