I find that casting Acid only sometimes gives feedback on damage and other times there is no damage message as well.

This was not the case pre-patch 1

I can confirm this with cold damage aswell on my toon. It will say I sucessfully cast my spell, however I will not recieve a notice (either above mob's head or in sys panel) that I have done any damage to it. Only has been happening post patch 1.
