Just because you did something once once does not mean you can do it every time or even the majority of the time. Only two teams in the history of the NFL have lost every game during the regular season. Point being, a bad team can sometimes beat a good team.
Troopers can beat the event, sometimes on your first try. But, they are not the ideal lineup. I completely understand that you want to continue to use troopers and that's cool. Just be prepared to get frustrated cause they will lose a lot! Fair? That's a matter of perspective.
Are two omegas exciting as a reward? Nope! But two omegas are definitely better than no omegas, which was the option before they started doing the mythic events. Given the choice I'll take the two.
