I'm not asking for Fantasies (that is only showing on 2 or 3 fights out of all our logs lol but Promises - if you have tips for my hunter also (Fantasies) - feel free to give them, because i'd like to be better also however, take note that it is my alt and it is also undergeared (all logs with my hunter is 547ilvl without meta gem which i only just got) and i've been learning it so we can help make eachother better and see where we may be going wrong.
