So unless you claim the trophy, killing FT doesn’t count as a kill “most” of the time.
I have had two matches where the bomb killing FT gave me the FT kills, but apart from that it’s only trophy collections that count as kills. (yes I’ve killed lots more FT with the bomb but they only actually got registered in two matches, perhaps that was actually the bug).
whole FT can be killed by Pred, but 0 FT kill count…
I even had one match where I collected 3 trophies and just for fun executed the last one on the ground next to the radio with the bow, the bow kill didn’t count.
