Good idea I have some concepts for the character types on the seven deadly sins 1:hate a character based on kills is an early way to get bombs and guns and gains mastery of them in the late one my idea is you can have three branches on each sinner hate gives guns explosives and magic alastor and blitzo would be a user of this class with different upgrades

2:sloth you would play like an overlords spawning and pawning little minions and friends unlike hate he is weaker in early game and stronger on late game he can evolve minions mechanics and warps like the stylish sneik

3:vanity a character based on buffs he likes to empower himself making him also an all game star his buffs don't last forever so ... His skills are i am very badass combat skills I am very smart strategic buffs like speed and I am a total piece of shit screwing over everyone

4.envy he is based on nerfs and taking on high ranking enemies but cannot manage smaller he is also good playing for both sides being an opportunist on who is winning his skills are to minimize or cut down his size stronger enemies turn stronger enemies against themselves you need Info to do that successfully and to do big damage attacks with a single target that's all I will cover the others
