The reason there is a right and wrong answer is because of the lack of granularity of the core system behind. For instance if just taking the latest role actions they introduced in FL pvp, there is no right or wrong answer for a lot of them, say for tanks, taking Rampart or Rampage isn't a matter of right or wrong, but a matter of playstyles and how well it meshes with specific jobs or group compositions. You won't see that much in pve because the current pve only has one single metric: standing in the correct spot and doing damage.
