Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

Hello, so I have three build concepts which are kind of similar (Ranged sneak attack/hips)

The first one is a classic rogue bow sneak attacker : http://nwn2db.com/build/?289396
The second one is a take on the crossbow sniper : http://nwn2db.com/build/?289831 (I read somewhere that arcane archer works with crossbows)
The third one is an esoteric take on the crossbow sniper with some warlock for haste : http://nwn2db.com/build/?289401

Now, I'm kind of happy with all of those three builds, but if you have any suggestion to improve them be my guess. For the third one, assassin levels aren't mandatory, but i'm a big fan of hips with ranged weapons.

Throw your suggestions!

Are you okay with the 20% XP penalty on the first and second builds? The third build has a 40% XP penalty. I think you will have a pretty slow go after you hit epic levels. I like UMD for any build, it just gives you more options with scrolls. I believe tumble is only good up to 30 points and gives you the max of 3 AC. I guess it all depends on what your expectations are for the build.

I really don't mind the 20% xp penalty, that''s like only 1/5 more mob to kill which will just give me more gold .

And I would like to be able to solo most pve content on server and be fairly viable in pvp with those build.

I'm planning on playing one of those three, but I'm not sure which one yet.
