My son, who is 6, loves playing D&D with myself and his older brother. He is all for creating a full fledged character, and for the most part understands what is going on. However, during play, especially combat, it is difficult for him to make full use of his characters ability. Being 6 his ability to implement strategy, tactics and resource management is limited. We will offer hints to help him, but many times he has already decided his path and just wants to play. I don't really blame him for this, it's what we all want to do :)
So the question is, are there any homebrew classes that are geared towards being easy to manage, but are not penalized for there simplicity. For instance, he likes using melee characters, So I was considering creating a 'Soldier' class that basically starts with 2 d10 hit die, and maybe a +3 proficiency, but no traits or special abilities. Would this stack up well against say a level 1 Fighter? The next question would be how to level him, maybe a combination of stat bonuses, proficiency bonuses and extra attacks in lieu of archetypes and what not.
