D&D 5E Rule of Three 4/4

[Mistwell]

This is exactly what I was hoping for. Anyone should be able to do things like push, trip or disarm, but fighters have a big advantage in being able to combine those things with their attacks.

I agree. It's a good compromise. And, I can think of a lot of times I'd like to do one of these things instead of, say, extra damage. But I think that trade-off is a good one.

You are correct if you are talking about the probability of seeing at least one crit. If you are talking about the expected (mean) number of crits, 6 times 0.15 yields the correct value of 0.9 crits per round, on average. (See also http://en.wikipedia.org/wiki/Expected_value#Linearity)

The 38% of rounds with no crits are offset by the 22% of rounds with multiple crits.

You are correct sir, but in my understanding they were talking about probability in one round, if it were the mean probability chance than we wouldn't had anything to argue about, one crit a round doesn't realy add to much, Especialy since it doesn't take into account the fact that some of the attacks might miss all together, unless I was very mistaken in my comprehension of the argument (a good chance since I've been on pain killers for a couple of weeks now)
