I find that due to channel energy being so strong that clerics get pigeon held into healing in circumstances. So I went here to the forums to see if I could find any threads and see if I missed something. Short story, I did but I still feel a change is needed.
I found that out of the four classes that can heal, clerics were fully capable healers and druids and sorcerers were made to have other possible roles with healing (damage for druid and sorcerers are just general spell casters) and at the bottom of the casters is bard when it comes to healing, but they're meant to support and buff.
This lead me to wonder if they were equitable instead of equal. So I thought about it for awhile and came to the conclusion that yes, it is for druid. For bards it's not in most circumstances and sorcerers just get a bum rap.
Thus far I only came up with a fix for bards, and I will test it out soon, but for sorcerers I just don't know.
Those wondering, the fix for bards is to add a small scaling temporary hit points on inspire courage. Probably being 1d4 and the usual scaling for cantrips (3rd adds spell modifier and each appropriate level after that increases base) making bards better in marathon scenarios and still keep the flavor while leaving clerics as the best in most scenarios (as I feel that is the intent for clerics).
