Auto Blitz Hunter/Sniper (kinda)

[Fellhound]

So I've got plans to make a hunter/sniper that's mostly agi/dex with a bit of luk to trigger Auto Blitz Beat.

I'm not planning on doing crazy amounts of damage with the auto-blitz, just looking to stun mobs in PvM.

Speaking very generally, my base stats will be:

Agi: 90+
Dex: 90+
Luk: Around 30
Everything else: Low

Does anyone have any feedback for my plan?

Also, does anyone have any suggestions for gear or cards that might be useful for this kind of build?

Thanks in advance.
