I'm starting to like dserv as a talent personally. 1. New beefed up demon to use as a main pet or 2. Shorter CD on the guardian's if you use dserv with goserv or 3. Leave em alone and go back to the 10 min CD guardian and use the standard options. Gives us a lot of flexibility and utility. As long as the numbers are tuned correctly I think this will be my default level 100 talent for Demo PVP unless 1 of the other 2 talents are just too bursty to pass up.
