Your build has character, that's for sure. It actually gave me a couple of ideas that I might try later on. Here's some notes:
I think that you're spending way too many points to reach stuff that really won't be beneficial enough for you. Increased radius might sound like a good idea but I think you're going overkill on it. I would save all the filler points and ignore mana regeneration (especially since you already grabbed the one from the templar).
I would grab Inner force, along with the two nodes next to it and focus on auras that will benefit you greatly (Grace, Anger, Wrath, Discipline, Purity etc). Your damage is fine so don't worry about that - your main damage output will come from gear, not from passives. Since you're going 2H, you should really prioritize survivability and should therefore start heading towards the middle parts of the tree (that's where all the juicy health-stuff lies). You can also grab 3x10 Elemental Damage nodes and some life regeneration nodes while you're there.
You have a solid thing going on, definitely. I'm just not a big fan of you going through the Witch-tree with the battle plans that you're going for.
