Sort of wish some of these options provided a bit more flavor to the ranger. At the moment bounty hunter and ranger knight are sort of the only ones worth taking because they actually give really nice passives with Thieves can't and heavy armor. The others don't really add a lot. Mage breaker has true strike which isn't very good, keeper of the vale has protection from good and evil which is easily acquired elsewhere, and sanctified stalker has sacred flame which is low damage and very easily saved against. The extra boosts to proficiencies are also super minor (+1 I believe).
I would sort of like if these favored enemy bonuses were rethought a bit. My first thought would be to expand the ranger spell lists a little bit depending on favored enemy. For example mage breakers would have the option to pick something like silence as a spell when leveling up, or sanctified stalkers would be able to pick guiding bolt. Something to set these three aside a little more than a protection spell that isn't particularly useful and easily cast elsewhere (Keeper of vale) or cantrips that will likely never be used (Mage breaker/Sanctified stalker). Would be curious what other people think?
