Also ze double post.
Personally, wished a long time ago that devs would implement Native American (Mayan, Aztec, Tribes) stuff. That would've been so great but lots of the boring same build and same meh boring european gear wouldn't have liked that.
But here's a theme build i used. Native American Axethrower.
15/24 build. 6 Riding, 3 Powerstrike, 5 Powerthrow , 4 Horse Archery, 5 WPF. Put all WPF into Throwing.
And for gear you'll use a courser most of the time but when you're short on gold you switch to Rouncey/Palfrey. And use 3 stacks of Heavy Throwing Axes, 1 Fighting Axe for melee and to pick off runners and be a good melee weapon instead of the HT Axes melee mode.
And for armor you'll use nothing except Hide Boots/Nomad Boots or Hunter boots whatever you'll like and nothing in hand armor slot and either nothing as head armor or deli hat if you want. And as for body armor i recommend no body armor at all but if you want one i'd recommend Pelt Coat or Khergit Armor.
