So, I'm still working my way through the playtest documents (loving them so far), but I had a question about the advantage/disadvantage mechanic. For those who haven't seen it yet, advantage means you roll two d20s and take the better roll, and disadvantage means you roll twice and take the worse roll.
Then, in reading the conditions, I saw that Prone still applies a -2 penalty to attacks, just as in 4th Edition, rather than giving you disadvantage. Blinded, on the other hand, gives you disadvantage on attacks.
My question is, what is the numerical impact of having advantage or disadvantage, on average?
The average result of a d20 is 10.5. What's the average result of MAX(2d20) and MIN(2d20)? I'm not enough of a dice probability guy to know off the top of my head.
