Extremely lack of luck vs bug?

[geri96]

Yesterday I bought 10 rare souls with ironite, and out of 10 summons 9 were extremely strange. I got 3 series of green 3stared cultist, blue 3 stared cultist, and red 3 start desert warrior; in this very order , repeating themselves 3 times in a row. What do you think? Is this normal?

Those are some of the most common "rare" soul drops so I wouldn't say it was a bug.
