great, i as waiting for a way to get fw4, not that hard though, but its cool
at the moment most lvl 20-22 players have not to do in arena 20, they just cant stand the dmg from npcs,
even for me that have def skill over 50 and lots of fws, still a dificult task

i suggest to add medi npcs on 20, at last can save some repair time for players
