I would advise doing everything you can to beat Twintania before 2.2 so you can immediately jump into the fray of 6-9. My Free Company's current goal is to get everyone we can the Twintania win at least once before 2.2 hits -- even if it means some of us missing out on a chance at a weapon. I believe those weapons will, sadly, be obsolete once the iLevel cap is raised although I hope I am proven wrong.
