Pippin low atk is already been expected as its a fengshui class not a normal healer class, her class cost alot lower afterall.
I should already be glad that the atk multiplier is 2.2x and heal 2 unit at same time, she should still able to reach around ~700 heal during skill activation @ AW50.
As for ability, i know it say all fengshui class deployed, but that doesn't matter as whats important it affect herself thats what important. At least its tons better than AW ability that situational use.
And yes your dedicated healer is already a strong unit, don't think you want to give up the spot for 2nd feng-shui

(i though ur main feng-shui will be Mia for that 13%G)
