This is from another thread, but I still think it's valid.

"Frontlines seems to be defined by the DRK tactic, at least on OCE, and I don't see that as exactly healthy PVP balance that there is such a dominant tactic."

Currently, at least to me, the DRK tactic is so dominant, it defines how you play FL. Follow the DRK, support the DRK, that's how you increase you chances to win games.
