They will add some goofy house rule for assassins.
Probably the ability to poison barrels to produce a toxic cloud and maybe a subclass specific spiked ring so shove can have poison damage added to it. (I do not wish for more cheese, just preparing myself for it anyway.)
What about Paladin/ Warlock? Pretty strong but horrible thematically.
Works great for a Conquest paladin.

Celestial warlock probably would work for a good aligned paladin, maybe even Archfey.
