Two weeks ago I completed 10 2v2 arena matches, but I got no chest reward in "Conqueror's spoils". Last week I didn't do any arena and today I was able to loot the chest. Is 10 arena matches even a must? In other expansions you had to do at least 10 arena matches to get rewards.
Just to mention that two weeks ago I didn't complete weekly 500 conquest bar, but last week I did. Is that the requirement for getting chest reward?
It's confusing. Could someone explain what are the requirements to loot that weekly chest?
