i would say make them all elemental. You will be able to quest far faster all elemental. I have 4 shams and a pally at lvl 62 now they are all elemental. I can clear up to the first boss in ramps (haven't tried the boss yet), but like everyone says don't underestimate
4 x lesser heals. Even though they are dps gear the +spell also go to healing (just not as much as a healing item goes). My pally would be at almost 0 health. I hit the lesser healing and he is at full health. I don't know if this will be true when i get better items later down the road though.
