Why is you decided to include SCAG’s subclasses in XGtE?Four of SCAG's most popular subclasses appear in XGE. They're a good fit for the game as a whole, not just FR.

Done! Short version is I would like more classes and specializations. My group and I have played absolutely everything.

Good thing Xanathar's Guide to Everything includes over 25 new subclasses!

It would have been nice if all the SCAG subclasses had been included, if for no other reason than Adventurer’s League PHB+1 rules.
