SB Marauder (viable?)

this is my passive tree build
its based off the new gem searing bond
so im still trying to figure out what i should

now im wondering if its even viable, is the passive tree well constructed?
and do you guys think it has any potential?


another question is what type of dmg or weapon yields more dps when using totems?
is there any type of weapon that does, if there are which ones are they?
