They did it :O

Meh, still requires you one specific build. Still prefer just first hit on your turn.

 Uh...if I crit, is this damage boosted?

any dice rolled when the attack is made is boosted by crits.

Magic Missile≠Attack

When? How?

So... They just superbuffed Magic Missile.

 Does an attack by definition have to have a Attack Roll?

Magic Missile does not have an attack roll, just damage.  I don't see this working with Fireball for example.

 I believe so.

Critical Hits

When you score a Critical Hit, you deal extra damage. Roll the attack’s damage dice twice, add them together, and add any relevant modifiers as normal. [...] If the attack involves other damage dice, such as from the Rogue’s Sneak Attack feature, you also roll those dice twice.

Yes, an attack by definition has to involve an attack roll. This spell does not increase the damage of things that aren't attacks, which would include Magic Missile and Fireball.
