ArenaNet:Guild Wars 2 suggestions/DustWalker

(Discussion)
Dustwalker is a profession which uses dust to make weapons maybe giant rocks and shooting it to the target or to blind the enemy and a knock down skill could be like this example: (the next time your gonna be attacked by a melee attack the attacker misses and you get teleported to a random location) when he does slash the sword goes trough the other player with the dustwalker and where the sword or axe passes turns into dust then the dust gets blown away by the wind and the player with the dustwalker gets teleporter to a random location and the attacker gets knocked down cause he thinks hes gonna hit flesh but hits air so he gets knocked down by hes own power but when a range attack hits him the same thing happens but the range attacker doesn't get knocked down and a running skill example: ( you move 33% faster and every time you get attacked by a range attack you disappear and teleport to a random location in front of you for 2 times) of course the enemy has the re-click them to keep attacking him and an example of an offensive skill ( the next attack misses you and you get teleported to a random location and the attacker gets 40..50..100 damage by your dust) and the dust goes trough him and back so a duel attack but together its like 40..50..100 damage and hes appearance should be like that there's dust coming out of hes cloak around hes feet,hands and head


 * Why this is a good idea
 * the appearance could do enough so players could just choose him cause he looks cool
 * new profession never seen something like this in any game i played


 * Why it may not work out
 * its possible not to be able to make this realistic cause a game always have lagers so the transforming to dust could show later then normal
 * May be too powerful
