This is the entire reason our Emp set bonus is mediocre. It's only useful for Haste / Refresh cycles, it ~would~ be useful on Regens but SE only gives us tier II. Everything else is self cast only and doesn't get the bonus effect. And assuming SE swept in overnight and made our self cast bonus's "other" cast-able, you would be stuck using max potency and only getting the feet / cape bonus / head bonus.
Head: Pimp Hat +1 (FC effect)
Neck: Enf Torque (+7 skill)
Ear1: Augmenting Ear (+3 skill)
Ear2: Loq Ear (FC effect)
Body: Relic +2 (+15 skill)
Hands: Relic (+15 skill)
Ring1: doesn't matter
Ring2: doesn't matter
Back: Emp cape (+6 skill)
Waist: Olympus Sash (+5 skill)
Legs: Potent Pants (+15 skill)
Feet: Emp Feet (+15 skill)
+81 in Skill
+30% Duration Bonus
8/8 Enh Merits = +16 skill
Total: 501 (Capped potency)
Not much room there to swap in body / hands / legs for Emperian set bonus without majorly gimping your buffs.
