Even without parser, people will find other ways to call out other players such as their gear or number of times they died.
Perhaps something like the mining base defense ranking at the end but instead it shows the top 3 player's DPS and your own rank but hides everyone else so you can compare yourself to other people to see if you are actually pulling your weight or not. Because a common thing I been seeing on forums is that people think they are doing good because they didn't die.
