Fireball Marauder?

Don't know why I can't find a fireball marauder build, so I decided to make one for myself.
However, I am not sure if this is a viable build in later game, so I want to ask for some opinions.

This is around 80 points spent, I haven't decided on where to go after.
Perhaps towards HP regen in duelist location?
and then maybe the fire and aoe nodes in mage tree?
