Don't want to create other topic, 'cause it'll have same name.
1) About "Disarm". You could just kill all ammo in weapon by this, not drop it. So victim need to reload it. Also people say "fast shot handtohander > aimed handtohander", so "Disarm" will be aimed attack at left/right hand, so make fast shot handtohanders a bit weaker.
But really, I don't understand why fast shot affects unarmed/melee weapon...
2) At San Francisco or New Reno apply/reborn boxing/martial arts thing. You'll be allowed there only with very high unarmed and special STR/END/AGI. And, when you win some fights (in special created area for only that player, looks like ring) you'll get bonus to DR. But as i said, you'll need really big unarmed skill, and high STR END AGI. Also, may be, min. level. So any other character type, that focusing on other skills, like crafting, small, big, energy weapon won't get access to this.
I know, alot people was talking about New Reno boxing ring, or Junktown arena (or what was that?), and some moderator/developer said No. But this is other suggestion.
