ELI5: How are the current dungeons hard?

[jdtuggey]

My second comment is about the probability of seeing criticism in FF14 groups, which will hopefully address your main point. For any player to see criticism occur in their group, they must be in a group where two events simultaneously occur:
- Event A: there is a player who is willing to criticize an unskilled player
- Event B: there is an unskilled player

The probability of two events occurring simultaneously is:

(Probability of Event A) x (Probability of Event B)

Note that both of these probabilities are less than or equal to 100%, meaning that in most cases when multiplied they result in an even smaller probability. This is why the probability of any event happening will always be greater than the probability of that same event occurring alongside another event (provided that the "another event" has a probability other than 100%).

So if you're a skilled player, the probability that you see a player be criticized is:

(Probability of Event A) x (Probability of Event B)

But if you're an unskilled player, the probability that you see a player be criticized is:

(Probability of Event A)

Why? Because as an unskilled player, the likelihood of your being in a group with an unskilled player is 100%, allowing us to simplify the equation.
