Halfling archer ranger. I even made this build for a con despite people griping at me for such a "sub optimal build". My favorite character of all time was a halfling from Basic D&D and I wanted to convert him to 4th. In basic D&D, halflings got bonuses w/ all ranged weapons & had a high chance to hide/move silently in woods, so they were already "ranger-y". In addition, Basic D&D shortbows & longbows did the same damage, so it wasn't handicapping the character at all.
In 4th ed though, not only were the ability score choices sub-optimal (+2CHA? I need Wisdom!) the weapon choices were laughably awful. Had I picked an elf ranger, I'd get faster move speed, the wisdom bonus, and be doing d12 damage w/ my great bow. The halfling was stuck w/ a d8 dmg shortbow.
I made the most of the character though, by sticking to powers with low W damage and instead had lots of extra effects, or could be used with Immediate actions. The character ended up almost being more of a martial controller than a striker, as he could shoot at an opponent to interupt their attack on an ally, etc.
