While I appreciate Larian's intent to include every class, sub class and race from PHB, i find that its choice of sub classes is very limiting. If you want to build melee spellcaster, for example, you couldn't do it in PHB.
There are plenty of options of building melee spellcasters in PHB. Even if one wouldn't count half-casters like Paladins, Arcane Tricksters and Eldricht Knights, there are full-caster options - Valor Bards, War Domain Clerics, Pact of The Blade Warlocks. Not to mention plethora of ways you can have a melee spellcaster with multiclassing. If Blade Singer or Hexblade were added, all those classes suddenly lose most of their attractiveness, in fact making the game build options poorer rather than richer.
As for Wyll, my suspicion is that Larian is still undecided on how Pact of the Blade will work in the game. I personally would just make Pact Weapon grant additional +1 to weapon enchantment alongside usual benefits. Then it would make more sense to build Wyll around melee (even with his current stats).
