A 4x2 is certainly not worthless at all. I have a buddy with a 4x2 that has full skids underneath and sliders. He drives over all kinds of stuff, but knows his limitations. He has a great time in his vehicle. Sure he can't climb over everything, but that's perfectly fine with him. It's what you make with what you have. So have fun with what you have and don't worry about what you don't. I have a 4x4 "S" and wish I had an OR with all the bells and whistles but when it came down to it, that was going to be a lot of hardware that would not get much use. The only reason I got a 4x4 was due to my job requiring me to get to the office no matter what the weather - otherwise a 4x2 would have suited me just fine.
And I agree with what has already been said, most of the time you won't be in 4WD, so don't worry about it.
