Yeah. But then you have to remember that when you're rolling to determine if the party is surprised, the Ranger's benefit applies to the whole party, but when rolling to see if the party surprises the monsters, the benefit is individual.
And since surprise is determined on a party-wide basis, that means that only a ... wait for it ... LONE RANGER* can gain the benefit of the surprise "advantage."
But then there's dexterity. Oh, and if there's a monk, time to break out the percentiles. Which is why parties with Rangers and Monks were colloquially known as the "Gygax Special."
*okay, or a group of rangers, subject to the strictures of multiple rangers traveling together. But that's not as funny.
