Zealot's Oath ES regen vs HP regen

Faith and Steel is a nice passive for ES-focused builds, and it's near to Zealot's Oath. Also, the 1% life regen node in the Templar starting area is one of the few life regen nodes that is near to ES nodes (the others are the ones in the Scion starting area, leading up to Shaper). So the location of Zealot's Oath is not completely unreasonable.
