well frankly i would cut those in half and merge them and add one more so you end up with 3 choices. Bounty hunter as far as i seen still doesn't work.
problems is some of those spells need a bit of a tweaking by themselfs like true strike with concetration is just bad.. Sacred flame could do with abit of a damage boost or lowering it and giving it extra effect. Lots of things they could do to make them better.
Bounty hunter works for me just fine! Did you check the combat log?
Just tried it again on the save i had. Apparently i had Sanctified stalker picked my bad no clue why. So no wonder it didn't work.

and sadly it doesn't work on other abilities/spells that need STR saving throws if it did it would be cool because hitting STR St is a nighmare as is, most of the time.
The ensnare is an active spell. Just like sneak attack they made it way worse. It should work the same way! As a passive on weapon attack easly done with new reactions. Same thing for hail of thorns. instead of letting me use it twice per turn by prebuffing it. Ow and then we have hord braker again active instead of passive lowering usefulness once again.
For some reason those are still all actives so the value you get out of it is smaller.
Like i said if we could pick two of those at the same time sure it would be ok. if not i would prefer Solastas Favored Enemies over this particular homebrew. The one DnD new hunters mark would be best though. That way i can at least keep up with berserker paladin somewhat.
