It may be a Tabaxi Hexblade. The sinister taint of the Hexblade combined with the personality of a cat.... So many possibilities. However, I have to see if it is possible to build a fun and efficient PC. If you can't get an AC 16+, it is hard to be a melee PC.
I have to see the details on the mechanics next week before I'd know, but that may be the only new subclass that hits my queue of characters waiting to make it to the table. The rest might still rely upon existing materials. I think I might consider a Kensei, a Divine Soul, or an Inquisitive - but only if the mechanics grab me.
