Defense from Hydrothermal Vent's attack

[V10lentray]

There are only 4 Trap cards.

3 of them are "attack type cards"

2 of the attacks are unavoidable, only hydrothermal vent is not.

I don't remember from the playtesting discussions, but was this just missed, or was "unavoidable" intentionally left out?

Could this be something to consider for Errata if it was accidently left off. It seems like it should be unavoidable, based on past card creation.

I know Hydro thermal Vent intentionally left out unavoidable. The fact that any defense can be used against it was also intentional. While this is considered one of the best trap cards because of it's lack of restrictions/high dice, it has the downside of not being unavoidable.

... which is somewhat ironic, since all 4 existing Hydro attack spells have the Unavoidable trait.
