Well, I have never heard anyone else getting 3 same slot items. Not even talking about getting same slot item 3 weeks in a row. "worst" rng I have ever had was same item twice in a row in BfA. What op is experiencing is certainly not something which is in "regular" drops otherwise we would have seen way more pots like that. People who get seemingly normal drops have no reason to make pots like this. People who do get "abnormal" drops - do. So even if there were 3 different pots like that it might just be that it's 3 cases who made a forum post while 10k didn't.
