Had the Foil drop twice, and Found Verdict drop ~8 times. Never even seen a Timepiece drop. My issue with the foil is the charge rate. I have a few decent DO fusion rifles that have a little bit less impact, but can get off two shots in the time PF can get off one. Unless you can really make full use of the perks(RR and GHF work against each other), the charge rate really brings the PF down a lot, compared to many other FRs.
