I absolutely agreee putting an incentive to attack the highest ranking server in the current skirmish (wxp, points to capture… as proposed earlier).
It would help correcting the imbalance / overpowerment that an underpopulated server has to face.
This is often a reason for players of said server to become frustrated, leaving the game mode, thus making it worse and harder for the remaining players. I also think that in the end it would make things for the higher ranked server more interesting as well. I find the game boring if you dont have enough people but as well if you just train and easily overroll anyone and everything.
Absolutely worth a try! I would be delighted
