It has to be also noted that there's no do-over for "failing" a pvp session. If you jump into any instanced pve content, minus potd/hoh, and wipe that content, you restart the encounter. This is usually the part where conversations start about who/what went wrong. In pvp, that encounter is final. Next encounter might be with complete new set of strangers, allies and competition alike so you can't go over what went wrong. Perhaps that's why they left this minimal parsing because devs knew there's not much the playerbase can do with it.
