I just did the 2x2 Batcave instance and the leader board scoreboard says I had three enemies knocked down but the summary scoreboard says zero.
I can say that anyone that will ever read the problem that you just brought up will know that it is the least of DCUO PVP problems atm,in fact we could argue that this is the very last problem needed fixing apart from the other 99%.
I know PvP is screwed up but since the summary scoreboard is new, I thought, perhaps, they were still debugging it and might want feedback.
no,hahahah they never want feedback,they have a little group that decide how pvp and pve should be played,eventually they will end up with just that little group of people on the whole server.
