Gage

Revenant is one of if not the hardest to learn. Executor ability to parry anything and can block most attacks makes it pretty easy to learn, and with an a ult that makes you immune to status makes him easier then any of the range classes. He also uses bleed weapons which is still one of the best status effects in the game. There's a reason why people can solo the game as him and not have much difficulties. In a party it's almost ridiculous with how much damage he can do earlier and late compared to the early game of any other classes.
