This is basically Lord of Heroes Nexon-ified. I love Lord of Heroes, so can see this game has massive potential, but it share same problem too. First, they basically cheaped out the gacha system by implementing a copy of every hero for FIVE elements. Secondly, fck element system, it's 2022 you'd figure that they should have found out something better by now. Lastly, it's Nexon, so prepare for super duper grindy game (well, tbh, LoH was kinda grindy af in the beginning too) and heavy monetization.
Well, feel free to play if you have no other thou.
