Investigator's Trap Sense

[Leona]

Greetings!
I would appreciate if someone could clarify for me the use of Trap Sense for an Investigator.

Spoiler:

Trap Sense: At 3rd level, an investigator gains an intuitive sense that alerts him to danger from traps, granting him a +1 bonus on Reflex saving throws to avoid traps and a +1 dodge bonus to AC against attacks by traps. At 6th level and every 3 levels thereafter, these bonuses increase by 1 (to a maximum of +6 at 18th level).

I have searched the messageboards, and the only places Trap Sense was mentioned was with Rogue, who gets Uncanny Dodge which was mostly perceived as a second part to Trap Sense. Well, since an Investigator does not get Uncanny Dodge, what gives?

How is a Dodge bonus useful against traps, which deny your Dex bonus, unless you know the trap is there, by which the flavor text "an investigator gains an intuitive sense that alerts him to danger from traps" makes no sense...

Thanks in advance :)

Where are you getting that Trap Sense and Uncanny Dodge have anything to do with each other? They're entirely separate class features.

I was referring to other messageboard posts about Trap Sense and Rogues/Barbarians, where people mostly answered to absurdity of Trap Sense with: well you get Uncanny Dodge 1 lv after so it's fine.
Unless you are aware of a trap, Trap Sense in itself makes no sense, which is why Uncanny Dodge filled in what it lacked, in a way. Investigators do not get the same luxury, so my question still stands.

What is the point of Trap Sense on an Investigator without Uncanny Dodge or a different wording on Trap Sense?

You get a bonus against traps because you have an uncanny knack for sensing when they're around.
Why would you also need Uncanny Dodge?

[Leona]

So you are saying the bonus from Trap Sense, which is a dodge bonus, applies even when you are denied your Dex bonus/flatfooted against traps?

[Warped Savant]

Ah, okay... I misunderstood what you were asking.

Trap Sense gives you a bonus to reflex against traps as well as a dodge bonus. If you're unaware of the trap then no, trap sense won't give you that dodge bonus.
But if you are aware of the trap and it goes off (say you failed to disarm so it rolls an attack) then you get the dodge bonus. Or if it attacks for more than 1 round you get the dodge bonus.
Not as good without Uncanny Dodge but not useless.

Would rather it was a bonus on disable device :P

The bonus to disable device comes from Trapfinding.
