Thanks for the insightful replies!

I took the plunge and went for it. The curiosity of running 8 characters got the better of me. My plan right now is to powerlevel this new 5-man team, then "mix and match" for PvE/PvP.
I'd like to farm ZG and AQ20 trash when it becomes available.
My guildmate runs a 10-man team, so we've been discussing running content together once I'm up and running. (Ony, maybe a PuG MC)

Thanks again for the replies! Cheers
