Frontlines: There should not be ANY rewards for 2nd or 3rd place

[Avarence]

This is a really bad idea. This is the fastest way to cultivate an extremely toxic environment.

How is telling people who ELECT to join a "team-based PVP mode" that they must contribute to said PVP or get nothing, toxic??
Even setting the dmg bar low; 100k dmg, would probably prevent 7 players per match from getting rewarded. (Dmg is an example, could be another metric)
Forcing them to participate or not que. Allowing someone who wants to play/try to join.
Enforcing people to do what THEY SIGNED UP FOR, is not toxic.

It is more toxic for a person to join a TEAM based environment, mode, game, or setting, and not do anything constructive to help the team.
