I’ve opened a few good g12 /+ 1st place rewards, but I see your point seems 4-10 get the stuff we want.
I also believed for a bit the lower ranking rewards were better but, we might be looking at it wrong.
Of course, there are 9 more slots to generate a greater out come then the first slot by its self. Giving a perceived feeling of better gear then the 1st top slot by itself. Place Rewards 1-3 are the same and all 3 should be compared together against 4-10 to get greater sense of value. When I did that... 1-3 win. Since the rewards are random, 3 or 2 maybe better then 1. And I’m okay with that.
