What I'll probably end up doing is piecemealing the content on DDB, for character creation. I've got a PC Divine Soul (from UA), already. I really liked shadow magic in 3.5, so I'm curious about the Shadow Sorcerer. War Mage was one of the specific 3.5 classes I wanted to see implemented as a 5E Wizard subclass, so that's intriguing. I liked the Horizon Walker concept as presented in UA, but no one has shown interest in it, in my game. More spells don't suck, either. At a certain point, either I'll have picked up enough bits and pieces on DDB that the whole book makes sense or it won't. I'm pretty bummed by the news that the UA Ranger won't be made available as a whole because that and the Favored/Divine Soul were the two things I really wanted to see come to DDB with this release.
