Warden class: Does the extra power draw do anything? What about archery skill?

[espenta]

I have soon saved up enough to go hero, and I'm thinking of choosing the Warden class because of the increased power draw and increased archery skill. But I have read on the forum that power draw is capped at 4 points higher than the required power draw of the bow. Is this correct?

I have also read that all bows in the game require only power draw = 1. Is it any point of adding an extra point to power draw when the usable power draw skill is only 5?

Is the reason for the extra power draw that there will be new items added for hero classes which will have i higher power draw requirement then?

How will the extra skill points in archery help? Do they increase damage, speed and accuracy, or isn't damage affected?
