PS3 targetting and interruptions

When casting a spell and your character can't see it getting interrupted is getting extremely frustrating. Even with clear line of sight if the mobs strays from the center of my screen I get spells interrupted. If a mob runs past me and I'm mid-spell I get interrupted. It is extremely annoying and needs to be addressed.
If I have clear line of sight, even if my screen isn't looking at the mob, my spells should go through.

In a fate this morning an archer was kiting a mob in circles. I dare say 75% of my spells got interrupted because the archer was moving. I was targeting the mob chasing her, but the principle is the same. I had clear line of site the entire time, but because she was moving my spells were constantly interrupted.

To me, this is a bug. It should be looked at. Please look at this issue! It is very frustrating.
Thank you.

I'm affraid this will end up in "working as intended" bin ... Really - as Arcanist / Conjurer / THM you simply need to have a good vantage point. I've not experienced exactly what you're describing but indeed loosing the direct line of sight = loosing the cast. The same goes if you move during the casting. Maybe making some video to show exactly what you think is wrong might help to clear this up a bit.

eeehh what she means if the target moves to left or right its gets interupted... same hapens to me on PS3 just cuss the monster moved a 1 step to the right or to the left its gets interupted..

Working as intended. If a mob is running to the left or right of you or even around you move turn your guy with it simply put.
