I've had everything equip, mix and match of both menagerie and Crown gear but always got 2% and 4% every other game which leads you to do 3 games per 10% which in total you need 30 games. I dont know how people are getting 5% It doesnt say exotics count more nor does winning. Its also work almost the same for Gambit if you have everything. 7% and 3% every other game, 2 games per 10% and 20 games in total
