Hello,
As far as I can tell after making a bunch of fighters and then trying to figure out where I could see the bonus from each fighting styles, it's in a different place for each selection, which is annoying as fiddle sticks.
Defensive (the one it defaults fighters to select), you actually can't tell it does anything until after you take off your armor and put it back on. If you do that and hold your mouse over your ac, then it will show the +1. So it looks like I found a bug relating to either the display or the application of that bonus. (I did log the bug.)
Archery I have to hold my mouse over the attack characteristic on the character sheet.
I didn't check duelist because I don't see a use-case for it unless it does more than I think it does. (Equipping 2h weapon, duel wielding, or shield always seems better than this)
Two handed specialist or whatever it's called, it shows up in passive features tab.
Protection shows up as a toggleable affect in the passive hotbar (like someone mentioned in this thread, thank you for that btw, I didn't know that hotbar existed).
duel wielding shows up if you have 2 light melee weapons equipped, then it shows the damage with the ability modifier.
I would prefer that I could easily see what bonus I selected on maybe the features tab, or if the features tab is meant for something more specific that doesn't include most of those options, then have another tab that does show like an itemized list of not only the bonuses that I selected during character creation but also when I level the character up.
I haven't done as much testing bonuses from leveling up, but I remember being confused about it at some point with at least one class/subclass. I don't remember which one, which I know isn't helpful, but I am including this because I think having this information in the same place as what I requested above for fighting style bonuses would make sense for whatever you select during the leveling up process.
The use case for this would be if I am coming back to a character that I haven't played in a long time and don't remember what my build was. Or if I wasn't paying as much attention during character creation as I should've been.
Thanks for reading.
