To be clear, we 3 players are camping kaotM without success (not kaotW). Many many kills, many levels made, no drop. We don't really complain (although we are more or less forced to give up such hard camp), we were just wondering if something is wrong.

--------------------------------------------------

Parenthesis :

I made some interesting maths for a better understanding.

Suppose drop rate is 1/n (with n an integer).

The probability to loot item in less than n/3 kills is about 28%

The probability to loot item in less than n/2 kills is about 48%

The probability to loot item in less than n kills is about 63%

The probability to loot item in less than 2n kills is about 86%

We have now a good idea of what an insane drop rate is : for example, if rate is 1/3000, making 2000 kills only gives you a 48% chance to loot. Making 6000 kills still gives you 14% chance to obtain nothing.

(For those who know, it's a simple use of geometric law, with the assumption that n is high enough; n>=150 already works)
