1. To give better rewards for wins/kills etc., it would just encourage more players to take the easy, high-profit, minimal effort premade option, which would push more regular and new players away from FLs
2. To reward by damage/kills would give some classes an advantage over others. For example, SCH is huge damage numbers for very little effort.
3. How are other contributions going to be judged? For example, a MNK using their LB and knockbacks to try to stop a particularly troublesome enemy DRK. They would be contributing to the team immensely, but that might not be reflected in the statistics at the end of the game.
Whether it is possible somehow to measure such contributions, we have no real way of knowing.
