Conjurer 0 start for leveling was so fast, u can watch Elite Act 3 I got full devotion point video to contrast your other characters.
Conjurer indeed faster than Ritualist & Cabalist. cause have high Elemental res reduce.
and Rituialist in leveling not have Ghol set for res reduce. but I think just normal speed for pass Ultimate.
u feel slow, cause ur Skill & Devotion not very correct, u can show me and I will do something for ur Rituialist.
leveling Pets 2 Blight Fiend + 1 Briathron + 2 Reap spirit + Relic Pet 1 + Black book 1
