Champion Capsule question
So, I been gone for about 8ish months and decided to come back and play on my account that only has 31 champions out of the 134ish (all the 450 to get back into ranked) . So I leveled 4 times since being back, and noticed that out of the 4 chests i leveled the champion shards they provided were all champions that I already owned. Now, that would be understandable if I owned a majority of the roster. However, since I own well under 50% of it, are the capsules rates skewed to give you champions you already own? Or is my luck just really that bad?
