Guild Wars 2

I can’t speak for other matchups but the general rule for ours is that one server will dominate the others. Rather than the bottom two then trying to attack the dominant force they will often fight each other, effectively fighting for second place and allowing the dominant force to build up an unassailable lead.

My suggestion would be for an occasional bounty event to be placed against the dominant force – for example to capture their garrison or other keep in their borderlands. The reward for this could be a chest / loot drop with an exotic and /or a small chance for a precursor or rare item etc. This should encourage the two losing servers not to team up but to race each other to capture this keep.

The most intense sieges I have been a part of have involved all three servers defending/fighting over a fortification and, if nothing else, this will increase the chance of this type of siege.

Of course this would need to be balanced with some incentive for a server to win the matchup and the “bounty event” – perhaps a similar reward as to succeeding to capture said keep.
