Another thing to note is to avoid using Medica II in situations where adds will spawn. For example, in Titan EX after Earthen Fury you have a couple of seconds to get the group healed up before the adds spawn. Medica or Cure III will do the job just fine, whereas Medica II will be ticking and will cause you to get a decent bit of hate as they spawn and may make it harder for the offtank to grab adds and might mess with positioning, which is extremely important at that point.
