Also sneak attack with ranged weapons is only good up to 30 feet, so your opponent can pretty much move over to you and put a hurt on you if you don't take him down with the first attack. And since you are "ray" attacker the odds are you do not have a lot of hit points (probably mostly d4s and few d6s) versus d8 and up.
You also have to meet the requisites for getting sneak attack and can't benefit from flanking since you are not making a melee attack (without some special feats or spell that is).
Your opponent also gets bonuses to AC (or penalties to your attack roll) for being in melee and "soft cover" if there is anyone in the way.
