You all are talking about realistic ... Why is so unrealistic that Halfling Barbarian being strong? Yes, they need to work harder to achieve the same goal as Half-Orc, but its suppose to be perfectly achievable ... their muscles works exactly the same. O_o
Have you never seen short bodybuilder? O_o Personaly im 198cm tall and i know a lot of people that is way stronger than me, yet way shorter ... since they are working with their hands a lot more than i do. So i dont quite understand what is so unrealistic about strong Halfling to be honest. :-/
It seem to me like you were forgoting that you usualy dont create Halfling Barbarian level 1 ... who allready have 20Str. And it seem to me like you were forgoting that level and ability score improvements are just reflection of his EXPERIENCE ... Yes, Halfling would need to work harder and it takes him longer to be as strong as Half-Orc, or Goliath, or Human, or some specific kind of Dwarfs (wich are lot closer to Halflings in matter of bodyshape, yet they are as far of them as the other ones that seem to "logicaly had to be a lot stronger") ... funny enough it takes him precisely the same time as most Elfs, and other races that dont get +X to Str. btw, but that dont seem to bother anyone.
I still dont understand why cant we change Race for our hirelings. Lets us play Githyanki as racist as they trully are!
