I really enjoyed Blyaunte's "Understanding Efficiency", it was refreshing to have a different perspective that included efficiency for the sake of having more time for fun things. While I personally would choose a slower method of training where I could do other things like watch a movie at the same time, when a player asks for help they don't need an opinion on how fun something is.
If I ever need advice on how to have fun, then I am playing the wrong game.
This is what really hits the point home, help and advice needs to be a place where the best methods are shared, separate from your personal opinion on what is most enjoyable. Fun is a variable depending on the player, statistics and game knowledge is fact that should be the basis for offering advice.
