Game Mechanics: Can't cast on mobs in water

[Xible]

Since the patch if you pull mobs in Timorous Deep into the water (like most kiters have done for years) you are no longer able to cast on them as they are half in the water and half out. The spell goes off and you get the message that you cannot see your target.

This makes quading/kiting in TD very difficult and I assume definitely not working as intended. I have not tested other zones to see if the problem exists there as well, but everyone in TD is pretty bummed as this is one of the only places for high end wizards and druids to level, and you have always been able to snare and nuke raptors, etc, in the water.

I apologize if someone already posted about this, I couldn't find one about it.
