I skimmed through the class writeups in the new playtest, and I noticed that the cleric's and the sorcerer's attacks and saving throw DCs do not scale with level. The text implies that they should scale with level, but the tables show that they don't.

Or perhaps they don't scale until 6th level? It seems strange that sorcerers have much lower saving throw DCs than wizards when their magic is supposed to be a barely controllable force that overwhelms them with use. I guess uncontrollable means that it's less effective? I expected it to be the other way.
