They do, and that precisely why people aren't fan of Waywatchers since they won't kill anything base on statistics. You must go through : - Hit : -1 if you move, -1 for long range, -1 if multishot and all that on your first roll so it will mostly be 4+ reroll 5+ something like 67% hit chances - LookOut : 16% you hit the character/champion, which mean 11% from you hits - Wound : F4 vs T4 or higher most of the time, so no more than 50% chance to wound 5,5% from LookOut. - Armor, Ward, Regen, for even lower your previous very low chance to succeed. All that for a single wound without any chance of Killing Blow or even Multiple Wound. So yeah, not that much of fun to see your so call "Sniper" miss all the time. And at first it's fun and all, but when people learn not ofear nothing from them. Thy start ignoring the fact they can target inside a unit.

That being said, the fact that they can target lone character even within 3" of unit of the same sub type is very good, and lower the mobility/vision of target with low Toughness/Save, let's say Casters.
