Hyper-roll is apply in 2 situations:
-
When you got at least 6 unit of the same type till Krugs. Some players try at 5 but it's risky. This has less than 10% chance to happen.
-
When you have nothing to lose: non ranked games or low division (when you lose few LP for a lose and gain a lot of LP for a win).
Any other situation hyper-roll imply a huge risk to finish 7-8th position.
In this case when more players have nothing to lose they will force egg-roll each time, so obviously at least one of them will succeed to have more golds units.
Conclusion: if you want to see less golds units then play ranked games and climb to higher division.
