UPDATE to V2
changelog:
09 OCT DW overload DoTburster
10 OCT 2H overload DoTburster–no DW dots 
12 OCT 1H overload DoTburser–weapon damage irrelevant to DoT, off-hand gives faster recharge for weapon skills
I’m toying with a build concept and would like feedback.
I’m currently playing a spellbreaker that is a lot of fun. It’s a hit-and-run style using overload and nightblade weapon skills, and I’m always surprise at how well the DoTs work. My concept is for a build using 2-hander with flat damage DoTs to spread weapon damage multiplied AoE DoTs. Overload is a must because it’s a single skill providing three DoTs. Exploring the options, spellbreaker seems like the ideal candidate. A druid might seem like another option, but it has fewer weapon skills for spreading the DoTs, and the shaman’s RR skills are less reliable.
I’ve searched the build compendium, and didn’t see anything quite like this, I’ve also found this thread, where the main conclusion is that the game offers insufficient elemental RR to make an overload build worthwhile. I have to disagree with that conclusion. moreover, that thread offered no actual builds and I’d like to remedy that here too.
so the build, it’s pure theory, I have none of this equipment, it’s just built on grimtools.

I only use the points that I thought would be minimum, so extra points could be dumped into supporting skills, or to make the base skills better; suggestions are welcome. I also only obtain the devotions I thought were necessary, so the additional 9 points could be expended buffing resistances.
nightblade skills offer as much cold RR as any class offers any sort of RR, and also a little fire and elemental RR. shaman has better elemental RR in the wind devil line, but the WD is less reliable than the veil of shadow aura that ensures anything in melee range is debuffed; my hypothesis is that, from an RR perspective, druid might be better for a ranged overload build, but spellbreaker is better for melee. From devotions, rumour offers cold RR, and viper and ultos offer elemental RR. The build could have as much cold RR as anything else possible, and it does mostly frostburn damage, so that’s important. the build also does respectable poison/acid, and as it turns out a lot of cold RR comes with poison/acid RR too. In all, the primary damage is frostburn, with substantial amounts of poison, fire, and electrocute, where the RR for each damage type is about in proportion to the damage output of the build.
as for applying the DoTs, the nightblade weapon skills are perfect. a typical attack sequence starts with shadow strike to move in an proc a single target DoT, ABB to proc an AoE DoT and lethal assault, RoS to proc another AoE DoT, then run or shadow strike away to pick off ranged attackers or avoid AoE. use mirror to make good the escape, or preemptively for safety.
