As per request, here are some random videos of me trying to Holy Melee Paladin (emphasis on "trying"). Also, inb4 git gud fgt. I only made 3 for now since I just finished up A4 Destruction with him. Survivability hasn't been a huge problem up to this point, but HMP's damage output makes me sad, especially Divine Judgement.
Early Charms - Binding of Baal
Early Charms - Azmodan
Finishing Act 4 Destruction - Chaos Sanctuary + Diablo
