Lost ark is a game of teamwork when it comes certain areas like Raids, Chaos Dungeon, World Dungeons, Adventure quests, Raids, and Other fun activities you do with other people.
Lost ark is more of bringing a community together, and NOT out DPSing your friends so that you can “think” you are the best. Everything is a learning process, which is improving yourself as a player with multiple classes the game has to offer, with different “roles” to play. However, if you feel like playing one class, okay.
Not only that, the game doesn’t allow you to solo through everything to a certain point in the game. If you haven’t learned that, you won’t have a good time playing the game at all. Take your time and have fun with your friends and other players! That’s what the game is about.
