i usually teach new players, but lately, its getting too time consuming, for example, i got 2 random new players to fill in for my group for coil group, and we took like 2 hours to get them to understand how everything works on turn 1, if i have got experienced players we could have time to run more turns that day, so yeah on harder fights you may need to learn it on your own if youre going into someones team or duty finder, if you want to learn head first, make your team and do it with your friends, cant be teaching these stuff every time.
