I didn't add any enhancements to the builder, as its all new to me. I'm wondering about the balance of the stats. I went assassin last life, so I would like to try something new this life. Any tips, advice, or coffee appreciated.

I can understand the first wiz splash to meet your AA pre-req; but what does the second get you?

If you're not going Assassin, then there's less incentive for staying (mostly) pure rogue. For "unconventional" rogue AAs, see my Triple A and wowo's rogue monkcher.

I ran my own variant of the Triple A staff build last life and it has a unique niche that is hard for other builds to get into. The combo of anti knockdown, insane (~60) reflex, high UMD, and high burst ranged damage allowed me to be the regular ELOB dog kiter for my guild.

Knockdown immunity and showtime's speed bursts should both be very nice on an archer.

As for your stats, dex imho is just a tiny bit lower than I like. I try to shoot for 30-32 on my archers, for to hit purposes, unless it is a monkcher.
