AW/PW have better solo target potential coz you know you can commit to target and you can slow/bleed it, nobody will make job for you and you have to take down the target yourself most of the time, while in mass pvp its mess, half ppl get considerably low on CP / HP by random AoEs or other ppl, so 1-2 stabs are usually enough to finish the guy, thus mobility comes in first place, in which TH is much better so you are faster in moving from target to target, also TH gets mirage which is far more superior in mass pvps as ppl will lose target after 1 hit/nuke, thus you can survive much more than AW/TH
sorry to burst everything you know about dagger (except sand bomb, i cannot take that one from you, trully insane skill)
ps: movie is done, missing some intro part and it can be rendered, i guess tomorrow will be upload?
