[Mage] Keeps watching combat

Hello guys,

I just started using HB. Started using it as BGBuddy and as i noticed, most of the times my mage targets someone and watches it for almost 10 seconds and after that it goes to melee range and start dps.
I tried looking for the options and found nothing related, also downloaded a new 'Amplify' Custom Class to see if that changes but nothing so far.

Any ideas how to solve this or is it just normal?

Thanks in advance.
