Spells: Line of sight on enchanter calm

[Caelor]

Several other enchanters have told me that they are able to cast the calm line of spells, and specifically the calm spell itself, through walls. I have also been grouped with clerics who have had the same thing targetted as I, while standing in the same spot, have been able to cast pacify on mobs that I cannot.

Anytime I do not have direct line of sight on a mob I get 'You cannot see your target' when trying to cast lull, calm or soothe. It seems to be using the same LOS rules as a DD. I am able to cast buffs through walls just fine.

So I have a 2 part question:
1. Is the calm line for enchanters supposed to have an LOS check in it.
2. If not, any ideas on what may be causing an issue for me?
