Yeah there's no trick to getting them only missions. With luck pvp ... I have 98 stamina when do a full stamina dump trying to get them I'll get 2-5. I'm 25 give or take on the leader board. I bought energy few times which sucks to have to resort to that . I'll try for top 50 then I'm done with events I miss old format already! I'm gonna by crates from here on out.
