That's interesting, because to my mind that's the single most interesting thing about the sorcerer. I love the idea of a class changing its playstyle over the course the day, going from being primarily a caster to primarily melee. Or even a different kind of caster; say a storm sorcerer being able to do gusts of wind and lightning bolts at-will as their willpower drops.
What if I want to play a more subtle sorcerer who uses enchantments. It becomes blatantly obvious who just charmed the queen if I suddenly grow claws in front of the whole court.
Check this report:I'm not sure I'm entirely thrilled with this sorcerer. The Magic-User is traditionally invested with a lot of offensive magic but suffers vulnerability in physical combat due to a lack of arms, armor, and hit points. Clerics, in contrast, got second-class armor, weapons, and hit points behind the Fighter but were full-fledged casters - albeit with way more buff and heal spells for the benefit of the group and less fire-power for themselves.
This Draconic Bloodline Sorcerer has better weapon and armor proficiency than the cleric, has the same hit-dice, a damage and damage resistance bonus, better to-hit than the cleric, and all the Evocation offense the Wizard has to offer. Other than the healing factor the Draconic Sorcerer puts even the War Domain cleric to shame.
It's not a bad concept, but this particular build needs to be trimmed back more to the War Mage scale - perhaps d6 Hit Dice, Medium Armor Proficiency, Shield Proficiency, Basic Weapons + Finesse Weapons, and no extra +1 to weapon attacks.

It pretty much confirms one thing,
Did I miss something? Where is the sorceror (and warlock) playtest info?
