Another thought, about spell components:
The playtest packs seem to be fudging what the Material component of spellcasting is. In the 2014 PHB, material components, when not assigned a gp value ("if a cost is indicated for a component"), are entirely cosmetic: they can be replaced either with a focus or with a component pouch.
However...
Conjure Barrage and Conjure Volley have a material component: "a melee or ranged weapon worth at least 1 cp." Given that a dart costs 5cp, and a club 1 sp, it seems probable that this wording is intended to get around the exception for material components. I'm not sure "a cost is indicated", but it's close enough that a minimum cost is indicated. Nevertheless, it's a bit of a fudge.
This, at least, fixes the mistake in Playtest5, where Memorize Spell and Modify Spell have, as a component, "your spellbook". Now that doesn't have a cost indicated, but it clearly isn't something that could be substituted for a wand, since both spells refer to a spellbook (sometimes "Spellbook", capitalized) in the description.
