Legend
Power sources had a favor and a mechanical identity. However the desire to "fill out the spreadsheet" kinda ruined it.
Divine powers dealt radiant or necrotic damage and had slight leaders aspects.
Primal powers focused more on fire, cold, thunder, and lightning and had transformations and summons.
If the Nature Cleric was Divine with Martial, Arcane, Elemental, Shadow, or Primal options based on domain whereas the Druid was Divine, Primal or Both based on who they revered, there would be a clearer picture of how they differ.
4E class and role design was inherently flawed.
Pages of powers required for basic stuff.
