It seems like there could be something done to bring styles a bit closer in effectiveness/use:
Fencing is the stand-out since it's only weak vs Mindless and has no MAP, size restriction, or 10-minute immunity. You can basically Panache cycle with this all day long as long as you steer clear of mindless things. No feat tax, it just works from level 1 on.
Braggart is pretty limited w/ 1/target and weak vs Constructs/Mindless/special training (whatever that means.) The language-dependency makes Intimidating Glare/Prowess a must.
Fix?: Allow re-use of the Intimidate skill to "harry" an opponent w/o out the Frightened condition? Or limit it to Frightened 1 only on a crit after the 1st Demoralize?
Gymnast has quite a few options but all of them are MAP based and size restricted. Titan Wrestler is an obvious choice to minimize the size restriction. I get that Gymnasts can target a specific save as needed but I think -5 (-4 w/ Agile) on your Attack after gaining Panache is a bit steep.
Fix?: Allow a non-MAP use of Athletics or reduce MAP?
Anyone have any other ideas/thoughts?
