So I just had a prolonged game where the FT won. It was a great match but I pushed a bit too hard at the end and was unable to finish the rest of the team when two of them were downed.
They then stayed to get everyone up whilst I self-destructed. And none of them escaped.
I got 14,000 xp for that match. I don’t see anything in the patch notes to suggest they made self-destruct kills count. Did it always count as a win if you killed everyone with it or something?
