Do not watch MrHappy videos. He is a very lazy content creator with bad editing that results in videos that take 30 minutes to explain one boss mechanic.

He has been popularizing bad strats his whole career like stacking everyone behind the boss for Titan (Hard Mode). Instead of taking one puddle attack and surviving because of server lag, you take 7 puddle attacks and get incapacitated.

I will always remember MrHappy being very disrespectful to other players at NA Fanfest the one year I went. Reconsider the type of content creators you support.
