Battle High is also a problem. I get that it incentivizes faster games and to seak each other for kills, but once a team is dominating in battle fevers, the match is usually decided. There is just no coming back unless the Battle Fever team neglects the PvE aspects in favor of killing.
It's almost more optimal to ignore any of the targetted objectives at the start to rack of Battle Highs/Fevers and then storm the targets later when you can crush them with the power imbalance.
