Stumps providing LoS would cut down the hunter problem significantly, but really the biggest problem is the damage and healing to HP ratio. Damage and healing is about 300-400% of what it used to be and health pools didn't increase much after wrath and ate a big nerf since BC days. That being said, certian classes *cough* warriors *cough* lost so many abilitys that big numbers are the only thing making them viable. There's no easy solution and I don't foresee any intentional improvements to low level gameplay. Either adapt or find something else to do.
