Rogue - Halfing or Barb

[Tappin]

From a non min/max'r point of view, is this pretty huge str/sta advantage of a barb a really big deal outside of end game content? As far as leveling, grouping, etc... What a barb be outputting much higher dps than a halfing?

I'll be leveling with a shaman and monk and have been trying to decide which class to make, and while I'm somewhat sure on rogue, and I like halflings, I'm not sure if I want to make a barb, unless the advantage is pretty game changing. I do like barbs, just not so much as rogues.

Thanks for the input!
