Dustnayple: This is true. If you come into the chat on Sundays, usually you can put in a few requests for farms. (:
As for the "rigged" odds, I'm pretty sure it's just the randomizing code doing its job.
If you roll a dice 1000 times, there is a chance that you will get the same number 200 different times. There is also a chance that you will get the same number several times in a row. I honestly think what you guys are experiencing is just bad luck. Randomization does not specify that you will get each of the 50 opponents exactly once in 50 tries. You will always have repeat opponents when randomization is in play, and you will never meet the perfect 1/50 odds.
maybe if you rolled a 6 sided die, that would be that would be pretty close to actual odds, (1/5 when the theortical probability would be 1/6) but youre getting something 20% of the time, when you should only get it 2% of the time. That does seem like its stuck imo.
Imagine out of 100 rolls on a 50 sided die, getting the same number 20 times. Not very likely.
