To keep it simple and short ...
I love what you did with Divine Smite ...
Set it to all those "reactions" (still didnt check if they consume reaction or not tho) ... but also kept active skill for those of us, who preffer using it that way.
Now, just Ctrl+C > Ctrl+V the system to Sneak Attack, add Off-Hand Sneak Attack, make it resource ... and i will be the happiest Ragnarok on forum! ^_^
//Edit:
Now when i think about it ...
Feel free to do exactly the same with Battlemaster Manouvers aswell.
