In 2.x I would and did transfer for statics. But now with the cross server raid finder and party finder I don't see the need of transferring anymore. The only time I would transfer again is, if that static is on a complete different data center, but to be honest, it's quicker to make an alt and raid with that. Saves you the $18 as well and you have no weekly lockout since you now have 2+ characters you could raid with. In the circumstance that this static breaks, you could just look for a new one and wouldn't have the hassle of transferring forth and back within a short time of period.
