Your aware how RNG works right? That's like saying "I only got 3 legs/rift in t13 and I did like 10... obv nerfed"
RNG is RNG, you can't create a case study to prove if something is nerfed a not with 10 runs. Hell u couldn't do it with 100 runs, or a 1000 runs. You would need 10s of thousands to even start such an argument.
Another example of this, is primal ancients have a 1% chance but by RNG you could get 5 within 10 drops.. Which represents a 50% chance. But that's RNG, and a reason as to why you can't create an argument based on such a low amount of tests.
