Hello, I wanted to raise awareness to what I perceive is an issue regarding class combo identity with the Defiler (Necromancer/Demolitionist). This isn’t really a balance issue per se, as I believe they are certainly capable of developing strong builds that can handle game content. However, I believe based off what I’ve seen that any build a Defiler can attempt, another class combo can do the build better.
The 4 main damage types associated with Defiler are Fire, Lightning, Vitality, and Aether. There is also Physical, Pierce, and Cold damage in the masteries, but there is no mastery access to RR for those damage types and will therefore be inferior to other class combos. I’d like to break down each damage type, how a build can utilize it, and why a different class could do it better.
Fire
Fire caster builds are much better supported by Elementalists or Sorcerers due to more fire/burn support as well as CDR, RR, etc. Necromancer skills add nothing to fire and have no skill modifiers making them fire friendly. Fire Strike melee/range builds are better supported by Saboteur/Purifier/Commando/Pyromancer. Vitality to Fire conversion exists on 3 items which can help somewhat, but only one of those is a Defiler item and is a stronger benefit to Pyromancers than Defilers, because they have stronger Vitality skills. Aether to Fire only exists in 15% ring slots, not enough for a meaningful conversion.
Lightning
Similar to Fire, but with more clear winners being Elementalist/Sorcerer/Ritualist for casters/melee. The only Vitality to Lightning conversion is through the Elemental conversion of the word of Inquisitor abalon. There’s slightly more Aether to Lightning support, but it’s better on a Ritualist.
Vitality
There’s a bunch of Fire to Vitality conversion, but Apostates take the cake with the Decree of Malmouth being for them and extra Vitality RR. Not to mention Conjurer’s/Cabalists/Ritualists being the obvious candidates for Vitality casters. There’s some Fire --> Vitality for Fire Strike supported, but that would be better supported by Pyromancers.
Aether
Spellbinders and Apostates trump Defilers in pretty much every aspect here for casters. Better Drain Essence builds, more Aether RR or support, etc. For melee, the much greater ease of Chaos --> Aether conversion makes Spellbinders or Cabalists better choices.
Unfortunately I have to go right now, but I’ll add my potential thoughts for improvement later.
