EA Scion needs help

Hi friends.

i played a EA Mara during the Beta and started a Scion some weeks after the release.

Last Patch they changes some Stuff about burn and degeneration. Now i have some questions, maybe you can help me there.

1.What exactly scales my EA explosion and burn?
fire damage scales EA explosion and the burn.
projectile damage scales EA explosion ?and burn?
did i miss something?

2. Is it a nerf for us or can we compensate it?

3. i planed on using Poison-arrow with conc-effect for some additional AOE damage. but i don't see a damage increase.
what scales Poisonarrow?

i hope you can answer some of this questions.

greetings Posewicht
