It was always been a constant that she has luck on her side granting that she does her move.

But after reading the Civil War series, she can manipulate probabilities of reality to her favor like letting a thunderbolt hit her designated target... a small time reality manipulator like the Scarlett Witch?

Is it cool or not?

Not cool in my opinion. We don't need everyone becoming some sort of reality manipulator. Domino doesn't need her powers to be anything more than what they have been for years.
