There’s a mechanic in the game that increases event difficulty based on how many players are present and participating in the event. Most people have probably noticed those NPC’s that seem to take forever to kill when there’s like 50 people around by now.
What if, in WvW the Keep guards and Champion, instead of scaling off the amount of attackers (which they don’t do anyway), scaled up based on how FEW defenders were at the keep defending?
To me this would not only give a nice time buffer for people to react in defending keeps but seem an easy way to slow down “Night Capping” significantly and give a hand to those few defenders that are actually awake against the Oceanic zergs (that seem keen on all transferring to the same server).
