Tabaxi 3 Bard/6 Dragonlord or Barbarian, using either Handaxe or Kukri, DEX based. Dragonlord is better, both enhancement wise and for having extra feats, but Barbarian has 10% run speed, which I'm addicted to.
1 point in Tabaxi gets you Dexterity to hit for cheap; it's the first core. Another AP makes feather fall obsolete, and a third gives you a cleave, but those are optional.
3 Bard gets you Swashbuckler which on handaxe or kukri gives 18-20 x3 crit, swift strikes Dex to Damage, and 10% doublestrike from dashing scoundrel if empty handed/10% dodge if using buckler. 13 AP You can also pick up a sonic damage imbue here, but not strictly needed if going Dragonlord which has a choice of imbues.
Tier 5 Ravager +2 Crit range for Kukri OR Dragonlord/Frenzied Berserker for +2 crit multiplier depending on if you went Kukri (Ravager) or handaxe (others). 34 points.
If you use Kukri, 23 AP in Vistani gives you 10% doublestrike, a cleave that gives you an easy to maintain extra 10% doublestrike, 20 melee power (SWF) or 20% offhand hit chance (TWF) and +1[W], plus Haste Boost. I've been going SWF, because I'm cheap and lazy and don't want to farm/craft duplicate weapons.
I guess Dwarf would be better for the axe user, if you have the racial AP to spare, but I don't really know off hand. Haven't built an axe build since I had the kukri laying around.
Feats are standard SWF or TWF, your preference. SWF with nothing in the offhand you'll want to pick up Offhand Versatility for your feats, otherwise it's the usual 3x SWF/TWF, Imp Crit Slashing, Precision. If you go another race than Tabaxi, you'll need Weapon Finesse as well.
The trade off is you're a bit squishy, being in light armor only, and you're a furry so everyone makes fun of you. You've got a few points to play with, so it's not completely AP tight.
