I think this would be a better idea, limit the amount of arrows you can carry instead of limiting the arrows 'in game'
And I think that 10-15 should be a max to be able to carry.
But............... I think todds words in an interview were more, 'they will be rare and hard to find' rather than 'we will limit the carrying capacity of arrows'
we will just have to wait for more info on this as I dont think they would limit the ranger/hunter characters to much with this in the end.
