Dual attack skills give 384 barrier with full celest gear. No one is ever going to have more healing power than that. Considering the insane rate that it degrades, 1k needs to be the bare minimum to even keep this into consideration, right? Even though every class except Ele AA’s for more than that.
I don’t know where you’re getting the 384 from but it’s just wrong. with 560 Healing power, below what celestial gets, I get 562 barrier per dual attack.
