Yes you are probably right and i have never written even one daut joke in streams but i enjoy as people use those memes everywhere. if you consider watching streams as way to relax, it is very understandable that Lord daut memes can be a way to express laugh and joy, and people by nature tends to do this, if people coming home after shitty day at work, this can be good way to have a laugh . Also i believe good portion of aoe2 audience especially Latin America, India, and south east Asia are young bw 15-22 so it is quite understandable. Fyi im 20 yrs old and love this game.I hope I don't get banned for this but...
The "lord" Daut memes are overrated and very childisch.
(He is an amazing player tho, I agree on that!)
