So you won 30 battles, and got 6 GLs. Somewhere in that you built the Heroic epic.

With no HE, you have a 1/16 chance of getting a leader per elite win. On average you expect 30/16 = 1.875 in 30 battles. The probability of getting exactly 6 is 0.93%.

With the HE, you haved a 1/12 chance, giving you an expected 30/12 = 2.5 leaders. Probability of getting 6 is 2.8%.

Very roughly speaking then, you have between a 1 and 3% chance of getting 6 leaders, depending on when you built the HE. That's not that implausible as a one off case. If it was happening

*regularly*that would be a different matter.
