The tactic is to simply find or create the weakest link and gang-up on them with your best effort to keep them stunned long enough to weaken them or score a kill. The first team to widdle down the other side wins or gets the upper hand if the losing team manages to widdle down the winning team to topple and become the next winning team.

It's the case in both CC and FL. Do your best to bully a single person before bullying the next. The first team to manage and keep at it wins.

This is making PvP boring because it repeats and why people find it frustrating to enjoy.
