Easiest way to level? Weapon/skills?
I just finished my ele and used zerker armor stats on everything with a staff. Had a pretty good time doing it and never felt all that challenged. Your mileage may vary but I destroyed just about anything I fought.
What healing/utility/elite skills?
Healing gliph for extra swiftness on overland pve is great.
staff for more aoe and better pulls.
LH and Glyph of Storms (on earth) for blinds if you go melee.
Easy mode to lvl on open world pve…
