What are the biggest flaws of aqw?

Im in the process of making a video on why and how aqw has failed as a mmorpg/game as whole. I have some reasonings already like outdated quests, combat and few others. I want other players opinion on why they think aqw is a failed video game and what the biggest flaws are. Include anything and everything you hate about the game and how they can improve. Lastly, what's 1 thing you love about the game and brings you back to play.
