In last 3 days I was able to collect almost all 7 dragon balls by only fighting time patrollers in PQs (and I don't mean the usual Dragon ball grind PQs like the explosion of namek, I was going through all PQs in their order on a new CaC).

I haven't gotten back into the game until a week or so ago, but months ago I had to grind time patrol encounters in PQs to get a single dragon ball and now I get at least 1 dragon ball per encounter.

Is it just my luck or was there some drop rate buff in recent updates that I am unaware of?
