Runes of Magic US / AU

Hi,

In the thread shown below, Game Administrator SaitoHajime gave some guidelines to be applied for LOS issues in siege. My understanding from the guidelines is that effecting towers/players with pets/spells is not an exploit, while effecting a permanent, fixed building is an exploit and frowned upon.

However, the post I am referring to is from a little while back and I was wondering if this rule of thumb still applies to LOS related abilities.

Destroying Throne through castle walls

Would appreciate a confirmtion that I am understanding the LOS issue correctly.

Thanks,

Tartax

P.S. I should mention, I am not looking for opinions on whether players agree with how LOS works, but just a guideline for how things stand today.
