Tempest con: Requires micromanagement and constant work due to elixir rotations. The overall theme of the spec feels like a full-time job.
Tempest pro: Best focus ability. Incredible burst damage.
Focus: 5/5
Passives 2/5
Skills: 3/5
Playstyle aggravation: High
Conclusion: 10/15 - insanely powerful focus, ok'ish passives. Skills are good but requires cooldown timings and micromanagement for max potential, which is more a job than fun.
Assassin con: Useless focus ability, however this means you can use mark of the rift instead since the Assassin focus ability is trash and not even an option.
Assassin pro: Powerful and fun skills, solid passives. (Personal opinion: Most interesting spec to roleplay).
Focus: 1/5
Passives 4/5
Skills: 5/5
Playstyle aggravation: Low
Conclusion: 10/15 - good passives, good skills but useless focus
Artificier con: Traps may look good. But they are actually kinda lackluster and ineffective.
Artificier pro: This spec has the best passives and a solid focus ability.
Focus: 4/5
Passives 5/5
Skills: 2/5
Playstyle aggravation: low
Conclusion: 11/15 - Lackluster skills but good passives and focus
