Instead of a leaderboard for “speed runners” who ruin the event for their teammates and prevent them from leveling up their Battle Pass, why not create leader boards for the following categories—which encourages teamwork (which is needed to successfully complete a run).
Medic:
Leaderboard for medics who heal the most people, and a second leaderboard for those medics whose med boxes get used the most.
Engineer:
Leaderboard for Engineers whose ammo boxes get used the most.
Assaulter:
Leaderboard for whomever gets the most kills.
Antitank Character:
Leaderboard for whomever gets the most kills with the antitank weapon, and a second leaderboard for those who get the most kills with the sword/katana .
For all characters:
Leaderboard for whomever destroys the most demon gates.
Leaderboard for whomever destroys the most bosses (not the last person who shoots them for the kill, but whomever accumulates the most damage points per boss).
Leaderboard for whomever revives the most teammates.
Leaderboard for whomever collects the most tokens throughout the event.
Leaderboard for whomever gets downed by the demons the least.
I think these leaderboards would both encourage teamwork, and also be representative of the actions you need to perform within the event to be a successful team. When people are speed running, they leave fallen teammates on the field without helping them, they leave tokens on the field because it takes extra time to collect them, they start rounds too quickly before their teammates are ready, etc.—which rarely promotes teamwork.
I don’t expect the devs to add these leaderboards for this event; however, please keep them in mind for future events. It takes more than just quickly running through an event game to be successful as a team.
UPDATE: Also, a lot of people are complaining about their random teammates during the event. Many randoms go AFK, quit, just play poorly, or are not team oriented. Perhaps the solution is to create a “solo” mode next time so we can choose to play alone, or play as a team (like we have now). Give us an option to correct this problem.
