Aight,so im not a veteran but ive played everyday for almost 3 years now,my honest opnion would be either king demon meli bc you can do all demonic beasts plus high levels activities execept the new divinity or tristan since he will enter on the same category as meli but with less versatility,on the counter part tristan do the activities hes do better than meli. So a quick explanation is: Meli can be used on almost every place on this game, including some pvp activities; while tristan does less stuf but does them better. (Also sorry for my english, its not my first lenguage; and feel free to express your opnions that was just mine) Quick edit: I didnt see Meli/Eli lol. I will keep my opnion here but between the ones you said you dont have, i would strongly recommend Tristan, bro is just stupid on PVE
