light of dawn broken?

i was doing it on another toon and instead of the 3 talent points it says you get as reward i only got 1 is that a glitch or have i not done the quest right?
What?

i rolled a dk completed the quest the light of dawn and instead of the stated 3 talent point quest reward i only recieved 1 talent point

You should have 25 talent points total when you're done with the DK starter zone. Is that not the case for you?
i had heard some where leaving the starting zone with 26-28 talent points

You heard incorrectly.
well thank you for fixing that up for me
The reason, you see +3 talent points as the reward is because before the new talent trees and points coming every other level. We used to get a talent point every level. That is the old reward before the new talent system. They just never changed it in the quest text.
bit slack of blizzard isn't it not to fix there quest text

Put in a ticket and let them know it's wrong.
