Magic/Range evasion focused build with 30/30/30 stats from gear.
You will be able to get all pieces from craft/main quest and litograph by the time you reach level 50.You need to fully trait your green gear for magic/range evasion though.
This setup doesn't require any dungeon or hunt pieces.
Lets be honest here. We not gonna invest more time to get a better gear than this in 7 days beta.
I think this blue/green gear will be fine for 7 days pvp and you will have decent hit and good evasion.
Half of us will need 2 days to even get to lvl 50...so this gear is perfectly fine for pvp.
