When I used the Barkshield I recall that very low damage would not interrupt me but heavier shots would, so I imagine bosses in PVE and Players in PVP would still interrupt you.
It's different for every item The AH is taking an average of what an item has sold for recently (within a few days to a week). As Dardove said, If an items market price has changed due to different reasons, the suggested price may be a fair bit off.
Blame the deleting of emails with attachments on the devs, even though there is a warning. Complain about sitting at the mailbox all day deleting mails, even though it is yourself who bought the 60 items that are attached to them..... Typical. It's cool to suggest improvements that could be made to the game, but don't…
Anyways...... the weapons should scale by race and/or sex. Even if this isn't believable, at least it would help eliminate annoying, immersion breaking clipping.
