Eh I like the idea of a bruiser-esque kinda rogue. With the stats I rolled, getting 14 int really made it that much more in my favor that she would be able to be better at combat. The rapier can't be used according to this for both hands http://www.d20pfsrd.com/equipment---final/weapons/weapon-descriptions/rapier
and even if it could, I still would need to take a feat to actually use it (overweight weapons or what not to lower the penalty for using a heavier weapon in offhand). Unless I use a light weapon in off hand, it just wouldn't work to use rapier as a weapon choice in terms of getting an extra feat. While I could get weapon finesse as a rogue talent, I would be cutting out of either weapon training (+1 attack is good considering lower attack rate I feel) or Resilency, which is pretty much +5 HP to my character if I drop below 0 once a day, which considering how I'll be up close and my HP rolls were anything but amazing, I think will be very helpful in more dangerous fights. As a side note, I noticed I forgot the -2 penalty on my weapons thanks haha ^^;;
The Sabre, sawtooth actually give with exotic weapon training the ability to use them and count them as Light weapons, thus lower the penalty to -2 instead of -4. While it has a little less crit chance then rapier, it has up to a d8 roll which I think more then makes up for it. Strength just will boost my characters damage up a lot more and with my dice rolls, it just made sense to me to go with higher strength (started 5 and +2 racial +1 level, it actually was my second highest dice roll not my highest) and skip on the feat for the sake of providing more bang for my buck when I do hit and helping to take out things faster since I'm a rather fragile melee character.
My character still will have pretty high dex in the end. If the game did go on so long, she would probably grab 2 more dex for greater two weapon which would give her +1 more boost. She will still be very good at traps but she will also be good in combat, hopefully having enough bang in her to take out things before they can strike her back, which will make up for her more fragile nature. Int wise, 14 seems like a great number as the +2 basically gets me enough for 2 more skills, which I have pretty well covered. If I was to take the second highest value, I'd only have 15 int which would mean I would have to invest +1 from my level in int to get the next higher value for additional skills which i believe would only come after level 4. Investing +2 racial to int just didn't seem like a great thing to do. The only real skill I could see using it for is Use Magic Device, which I don't think I'll have any use for at all unless this went into a higher level game. ^^;;
