Nothing wrong with being a casual player. Those MIs look good if you’re going to go with the Vitality caster route. I’d recommend focusing on the Sigil of Consumption as shown there. The single target damage of DoT Conjurer is kind of bad, so Sigil is almost required.
If you’re wanting to level a pet Conjurer in the future, I’d say go with this levelling guide and then look at Maya’s stuff later. Maya doesn’t really do levelling, so while the levelling dot-points in the Carnival will technically work, it’s an all-round horrible experience unless its your first character and you don’t know better.
Good luck!
