2.6 "KAMEHAMEHA" Self-Cast RF Scorching Ray Inquisitor/Chieftain

I'm also trying this build now (not using MoM for now, I have enough mana issues without it) and I was wondering if there's still any point in going all the way to Duelist for 2.6% life regen. There's an untapped 1% near scion (3 nodes, 4 if you grab the jewel socket) and 1% from Oak now, so taking those and not going to Duelist costs you 0.6% life regen but saves you 15 skill points (18 minus those 3 spent near Scion for the 1%). It does also cost you some increased life (38%), but most of that can be regained near Templar and Marauder for less than what it costs to get it near Duelist.
