I'm rather new to FA:NV (but not the series). I'm going for a pretty standard sniper build. Sneak around and pick of target. A bit like a stealth archers in Skyrim.
However, one guide suggests that you shouldn't go nuts on stealth since you will be so far away that they won't see you anyway.
Is there any merit to that claim? Otherwise I was thinking of going 100 (or close) in Sneak but is that wasting points?
