It's not a long delay but they've locked down the Head Start servers which will prevent the first wave of players from rushing to them. The only downside is if you're joining your guild and they are on a head-start server. Our guild has several players in that situation. You'll now have to wait about an hour longer before you can join us.
Eh, not a bad strategy or compromise. We were just discussing this in guild chat last night. What would today be like for us on a RP PVE server that has a 1 to 2 hour queue during prime time already, but it's a huge improvement from the 5 to 7 hour queues the first 36 hours or so into Head Start.
This strategy should lessen the new players coming into full servers. There's no point in waiting for the locked servers unless your joining friends and family.
