This is my first PaizoCon, and I'm stoked about it! Already have badge/banquet ticket, flight (from GA,) and hotel (in the block) booked and want to make sure I'm informed on how the deal goes down so as to garner the most gaming/forum/straight chillin' activity from it all.
Specifically, PFS. My group and I have run a few scenarios (strictly adhering to the rules as if we were hosting an open game,) but I've never actually played in an Organized Play Event, much less at PaizoCon.
Do I need to sign-up for PFS slots at the Con, or am I good to just show up and hop-on a table as I please?
The same goes for forums. Is sign-up required?
I like the fact that you're building your toon primarily around a character concept, and you should let that guide your decision. It seems like a decision you'll want to make for yourself.
Outside of that: Why tank your WIS if you're really concerned about your Will? Iron Will can be good to boost a fighter, unless you're really bad, which you kinda are. If you're gonna go that route, go all the way and get Improved Iron Will too (the difference it makes is so much more significant,) but I'd just play to my strengths at this point if I were you.
It all depends on what you want to play. You can build a really effective Pure Ranger, Ranger/AA, Pure Fighter, Fighter/ AA, Zen Archer, or whatever.
Really focus on who you want your character to be, what you want him/her to do, how he/she behaves and then pick whichever class combo fits that best.
You'll have more fun if you do.
Plus, if you're into MIN/MAXing, it's a great challenge, and great fun, to do so within the confines of a clearly defined character concept.
If you don't care and just wanna wail, I'm also a fan of the Zen Archer. . . just make sure to play a Dwarf with Steel Soul and Deep Sight--Nasty, Son!
Glad you get the chance to play a Dwarf of an unusual variety. You'll amaze yourself with the potentials [never forget Steel Soul feat (from APG,) it's a killer (or a saver, I guess, heh-heh.)]
A Dwarf would be better. Higher WIS = better Will Saves. +2 vs. Spells. Take Steel Soul (from APG) to make it +4 vs. Spells. Your build looks solid, though. . . for an humie.
