My 2H Ele Damage/Tanky Build. Viable?

This is my current theoretical level 60 build for a 2H Marauder built around using the Geofri's Baptism weapon. It focuses on heading up to the Templar starting area for Catalyse and the extra elemental damage to give Geofri's Baptism a little more oomph, along with taking points in 2H/physical damage and health/resistances for survivability - And of course, Resolute Technique. Feedback/constructive criticism much appreciated.
