Seems to me that healer was just being a jerk and mean -- there is absolutely no excuse to do the whole "I'm not healing _____" thing when playing with a newer player. If this is your first job and level 23 is your highest, the healer should know it and make sure to help guide you if she sees you doing something wrong, or at least give tips. Every time I do a lower level dungeon to help out FC mates, if we get other newer players I make sure to keep them topped off, especially if they are not synched down.

In the end, just a plainly bad healer with a bad attitude -- that healer doesn't represent what most of us are like ^_^v
