Regeneration Aura; change to Defensive Aura. Defensive Aura increases regeneration by 200% for all nearby allies. Increases All Resistances by 10% for nearby Pets (only). Increases All Defense by 7.5% for nearby Pets (only). Reduce CD to 3min 30s.
Adrenaline Boost; add a small All Speed boost for 1m 30s and a 30s All Defense buff (something like 5~8%) to your pets on cast, keeping the rest the same.
I feel MM Empathy is missing something that all other MM secondaries have, and that's added survivability through buffs/debuffs/cc. All Empathy has is heals and some buffs that are only really useful for other players. Now, that's fine if you're a defender; you have no pets, you only have yourself and your teammates to rely on. MM's, however, rely on their pets first, teammates second.
Now, Empathy could be fine, but currently I have all the defense enhancements for MM's, I have 6 slotted Maneuvers, I have holds + immobilize from my Ancillary pool, but my pets are always cleaved to death instantly in any slightly challenging content. The only way I can give my pets more survivability at this point is to get Injection (which I plan on doing later today), however that's only a single-target debuff, it doesn't help when my pets get swarmed.
So I want to suggest these changes to make MM Empathy provide more for their pets, while still being the more 'group oriented' secondary it's currently designed as.
