Blind is always far more fun and the way an mmorpg is meant to be played, you have to figure things out and think how to deal with the mechanics because sometimes the solution might be different based on your composition or even player preferences.

Especially if you got your own group of friends so you get to experience the above instead of just "lol copy what X streamer did, thinking is hard"

Now if I am doing something solo on duty finder I ll probably check vids for extreme and above since they are so very different and from my Ramuh extreme groups you definitely need a few ppl that know what is going on to explain to others, that one took me like 5 groups to get xD
