I'd say there's at least 100+ active pvpers per data center and more incoming when new modes / items release. The queues are just too long for frontline to be worth it. If gc restrictions were gone more people would play. Its rough to wait 30+ mins for a single match without being able to do much of anything while waiting.
As for incentive. It'd help if wolf marks were actually worth something. More items bought with the currency would be a great start.
