[should I go dual totem?] - help this half-arse lazy 'summoner'

my current tree:


going to finish the life nodes, grab the big ES nodes, max mana nodes.
currently play by Planting Flame Totem and casting Arc. - my two main damage.
minions as supplementary dps and meatshield - zombies, Ag, spectres and golem.

now I have plan to get Ancestral Bond so I can lay down 2 totems, and cast skeletons and SRS or curse.

question is : what is better?
casting Arc and get a Shock status for 50% more damage (from all sources above) (I Shock frequently, looking at HoT proc). potential to leech. have to watch for reflect/corr blood.

or

get dual totem. free to cast skeletons/SRS or curse. or buff like Rallying Cry/Flesh Offering,
no leech, no reflect.
