My suggestion is the ability to beable to zone into guild/raid instances directly from a teleport npc.
This would reduce people having to zone 2-3 times before going into instances, which equals less server load overall.
I am not suggestion the ability to create guild/raid instances from a npc, they would still need to run to the zone to create the instance, but rather ability to zone directly to the instance.
And since most people run 6+ char's this would reduce load many times over throughout the day
