Personally, I think the thing to do if you want to "reduce some of the tedium of playing a ranger" is to make rangers better in civilized areas. One way to do that would be to make bearcharge just as good in civilized as it is in the wilds.

Making snare better, on the other hand, would just make people even less likely to actually come into the wilds to fight you, which in turn would probably increase the "tedium" of playing a ranger at hero - IMHO.
