Will have to see the difference between base and t8 heals, but it seems likely probe buffs will have biggest impact in raids.
Situational: Suture (dispel), Dematerialize (purge), Paralytic Surge (stun), Extricate (pull ally), or Recharge (focus regen)
Curious: tier 8 Discharge's 50% more Power Cores could add up to more healing than Emission if Shield Surge/Field Surgeon spenders are a much larger portion of total healing?
Doubtful, but tier 8 Recharge's share to 2 allies could have a large impact too?
AMPs:
Protection Probes apply 1 Interrupt Armor
Healing an ally below 30% health also restores Shield (does Shield Surge proc this?)
Shield Surge and Barrier restore extra Shield to allies with depleted Shields
Shield Surge has 15% chance to refund cost
Every 10 sec, while you're above 80% health, sacrifice some health to restore double that to a nearby ally below 30% health (Repair Probes always attach to you, so they'll take care of this)
When dropped below 30% health, your Shield regens for 10 seconds. 30sec ICD.
you might want to drop empowering probes and put the tier points into repair probes then get healing nova for more AoE healing, the you have Emission, shield surge(might want to replace with field surgeon depending on how many each can heal), repair probes(their detonate can now heal others near them), and healing nova, all which are AoE heals
