1) AGM is not obtained with personal excellence but with high level people helping you.
2) Being a twink is by definition getting the most of your toon and being 24 is better than 20. Having a twink and trying to gimp it is just stupid.
3) Hunter a a winner class at this range and has a funny play style
4) About jump shot now ... It is kinda funny to hear about that. My first main char was a hunter and yes I learned how to jump shot in order to kill Artorius and finish the epic hunter quest.

Remember that having a f2p char is always your decision. don't blame other people for that. I will stay on 20-24 bracket as long as it is active.
