But greek heroes aren't supposed to be about bringing everyone the glory, it's about having the glory to yourself. There are 3 abilities that they get that can be used on allies, the Temporary Hit Point-Smite ability, the Aura of Speed, and the Shield-Attack ability. That's not really what greek heroes do in they myths. They don't make protecting auras around allies, or make their allies faster, or block an enemy's attack from hitting an ally and then whacking the enemy in the face. That's not what the greek-hero theme is all about, IMHO, it's about being selfish and a good person, while still thinking the whole world revolves around you.
I like that the Greek-Hero subclass is a paladin, but it feels like they were more focused on having it be a paladin than a greek hero.
