[RPG] Can you cast spells with a Somatic component if you’re holding a two-handed weapon

According to lead rules designer Jeremy Crawford:

The intent is that the shield hand can be used for a somatic component if the holy shield is used to cast the spell.

In a tweet exchange on 21-23 November 2014, @Sword_of_Spirit asked:

@JeremyECrawford Holy symbol engraved shield counts as material component, but does holding the shield replace somatic component also?

Crawford replied:

@Sword_of_Spirit The intent is that the shield hand can be used for a somatic component if the holy shield is used to cast the spell.

And further clarified that the shield arm cannot be restrained:

@Sword_of_Spirit You still need use of the shield arm to move it while performing the somatic component.

Yes you can cast a Bonus Action spell and still attack with a two-handed weapon.

Taking your hand off it in the first place should not require any action expenditure - you are just letting go of something, same as if you dropped it.

Reloading is part of the attack action with a ranged weapon. To reload, you must first take one hand off the crossbow. If your hand is already off the crossbow due to casting, why should it take any longer?

Even with a melee weapon, drawing the weapon can be done as part of the attack action, so putting your casting hand back on it should not take any extra time.
