What Healer kit (not encounter) change would make GCD heals NOT bad gameplay?

[Aravell]

Depends on how you define "bad gameplay". Do you mean "I lost damage", "I'm overhealing" or what? There's basically no way to make GCD healing not "bad gameplay" in regards to how the current playerbase thinks as they're too used to the abundance of free healing tools we have now. You can see all the calls for Toxikon to be damage neutral, nobody nowadays wants to lose damage when there's so many free tools that lose you nothing.

The only thing they can do without making damage neutrality is by massively cutting down the free tools on every healer, return to the HW style of healer kits (mostly GCD, limited OGCD). If WHM is to flourish as a GCD healer, every other healer also has to have a cost to their healing or WHM is made worse by default.

In short, if everyone loses damage when healing, no one will be lambasted for healing and losing damage for it.
