Empathy is pretty much the Mind-Support set.
At least that's my impression of it.
The AT that really needs a set with this sort of theme is the MM.
I really should do something about this signature.
Yeah Controllers and Defenders are also need it just for the sake of having a concept heroes but devs usually think about melee ATs when it comes to new sets.
PS: If you ask me Empathy is a wrong named set (who would call a heal/body modification (AB, Fort, + Regen and +Rec auras) set like that). Empathy is similar to telepathy but instead of reading thoughts it allows you to sense emotional state of other beings.
This set was proposed somme time ago under the name "Telepathy", basically a Mental buff / debuff set.
The powers were fairly different, but the idea is the same.. it allows "fully mental" Defenders and Controllers, possibly Corruptors if they get psi blast at some point, and importantly allows that concept "Mental domination" mastermind.
Basically a buff/debuff set for Conrollers, defenders and corruptors since Mind control and Psychic Blast dont have a matching power in defender and controller ATs (Corruptors will get it along with psi blast), so here goes:
MENTAL RESONANCE
1) Mind Siphon (ranged foe -RES psi, energy, toxic)
2) Psychic Barrier (Ranged ally +RES confuse, fear, sleep, psi)
3) Psychic Shield (ranged ally +RES Smashing, Lethal, psi)
4) Sleep Mind (ranged foe sleep -RES psi)
5) Mind Link (toggle: PBAoE Team +To Hit, +DEF all, +RES psi)
6) Mind Over Body (toggle: PBAoE Team +RES Smashing, Lethal, Psionics)
7) Distract (ranged foe -ACC, -Preception, -DEF all)
8) Free Mind (Ally +RES Disorient, Hold, Sleep, Immobilize, Fear, Confusion, +Perception)
9) mind Bubble (toggle: PBAoE foe repel, knockdown)
Thats all i can come up with, so if you'd like to add anything, please do
