Tempest Strike totem conversion

[Krag]

There are a lot of things I don't understand about the totem conversion node for Tempest strike.
For example, where does the damage from the melee hit go?
How does it work with all the nodes that mention a trigger on melee hit.
Why does it look like my totems are still ice when I removed all the tempest elements except for lightning?

It's very confusing.
