Doesn't Heal also have a lower base SP cost than Reconstruct?
So, again, tallying up how much worse Reconstruct is than Heal:
-Higher SP cost
-No Empower Repair feat
-No repair amplification enhancements
-No repair amplification gear
-Little room for casters currently using Reconstruct to add more AP into enhancing repairs (compared to heals, which dedicated healers will almost always have boosted)
-Can't remove status effects
-ONLY affects Warforged or fleshie artificers with the Construct Essence feat, rather than affecting (even if partially) all races
-Can't be used to deal damage (compared to Heal's ability to harm Undead)
-No Mass Reconstruct
-Along with no Mass Reconstruct, no version that scales beyond CL15
-Can't be used to heal quest NPCs that need protected in the vast majority of cases
Seriously, weigh all of this in and then try to justify nerfing Reconstruct in the same way that Heal was.
